How to Get Thunderstorm Thornblade in Aniimo

Thunderstorm Thornblade spawns in the Sea of Flowers, in the doorway of an abandoned stone house out in the iris fields, and the only thing gating it is weather: that region has to be rainy or in a thunderstorm. You know it is there before you travel, because the region roster on the world map puts a small blue rain cloud badge on its tile.

Despite the name, you do not need an actual thunderstorm. The card in the game reads Requirements: Rainy or thunderstorm, so ordinary rain is enough, and the Sea of Flowers rains often. The rest is a two minute walk: no quest, no item, no fight. The wild one stands at Lv.40, it does not attack, and one Aniipod thrown from behind is all it takes.

The hunt below is AniimoSync’s, recorded on 19 September 2026 on the live launch client. Every location, requirement and skill number was read off his screen rather than off the captions, then checked against the game’s data files, build 1.0.0.7, the same catalogue behind our Aniidex. Where the two disagree, this page says so. If you came here for Thornblade generally rather than this one form, the every Thornblade section covers all four forms and the Shining egg in one table.

How to get Thunderstorm Thornblade in Aniimo

Wait for rain over the Sea of Flowers, check the region roster for the blue weather badge, walk to the abandoned house in the flower fields and throw an Aniipod at the creature in its doorway. That is the whole route. Everything below is the detail.

Field	What the game says
Form	Thunderstorm Form, Thornblade
Elements	Grass plus Lightning
Role and stage	DPS, Nova Stage
Aniimo Location	Sea of Flowers, Lv.39~41
Requirements	Rainy or thunderstorm
Spawn Rules	Only one can appear at a time and it does not respawn
Spawn points in our data	One, in the Sea of Flowers and nowhere else
Level of the wild one	Lv.40
Fight required	None
Drops on capture	Pale Thorn, plus Form Research progress

One naming note, because it costs people searches. Launch renamed this form: it was Rainstorm Thornblade in the pre-launch tables and it is Thunderstorm Form in the live client. Both names point at the same creature, and our entry answers to either.

The weather rule, and why rain is enough

Rainy or thunderstorm over the Sea of Flowers. Nothing else. Click the badged tile on the map and the game prints the requirement in three blocks, and it is the second line that matters most: the word or.

AniimoSync makes the same point at the end of the video and it is worth repeating here, because the name misleads: it also only requires rain, it doesn’t need thunderstorming at all. Two acceptable weather states rather than one roughly doubles the number of windows you get, and his practical read is that the Sea of Flowers seems to rain constantly, which makes this one of the easier weather variants in the game to actually meet.

Weather in Aniimo is per region, so the Sea of Flowers can be under rain while its neighbours are sunny. In the same map shot, Rosetower Woods and Blitzwood are both showing a sun. When the rain clears, the spawn goes with it.

One thing our own catalogue cannot tell you here. The game’s data files record the spawn point for this form but carry no weather condition on it, so the requirement above comes from the live client’s card and not from our tables. The place is ours to confirm; the weather is the part only the running game knows. If you want the wider picture of how weather forms, terrain forms and Prismana forms all fit together, our forms guide is the one to read, and our Rainstorm Stellarys guide is the sister piece to this one.

The badge that says it has spawned

Open the region panel and look for a hexagonal tile with a small blue rain cloud in its corner. That badge means the weather variant is live right now. It is the single most useful thing in this video, because it saves you the trip.

The region label tells you the weather and the badge tells you a variant is actually available, which are not the same question. Our interactive map has the Thunderstorm Thornblade zone drawn on it, and that zone never moves. The badge is the live half the map cannot know.

Where Thunderstorm Thornblade spawns

At a small abandoned stone house with a red tiled roof, standing alone in the iris fields of the Sea of Flowers. The creature waits in its doorway. AniimoSync does not read out a coordinate, and the video does not show one for the spawn itself, so the house is the landmark to go on.

The house is not anonymous. Walking up to it starts a Journey chapter called Flowers and Thorns, Sea of Flowers, whose opening line reads: In an abandoned house within the Sea of Flowers, the Budsquires seem to be holding a tea party. Wonder what kind of story will they tell? That is a separate quest from the capture and it does not gate it, but it does confirm you are at the right building.

Our own survey agrees with the video on the important part. The game’s data files record exactly one spawn point for this form, inside the Sea of Flowers, and none anywhere else. The basic form has two points in the same region, a short walk away, and the Prismana form has one that sits almost on top of the Thunderstorm point. Compare them on the basic Thornblade zone and you will see how tight this corner of the region is.

Press Habitats on the map card if you would rather not eyeball it: the game drops a tracked marker on the exact spawn, the same way it does for every other weather variant.

Catching it

Approach from the right hand side of the house, or over the roof, so that you arrive behind it. Then throw. There is no fight, no weakening phase and no capture minigame.

The backstab is not flavour. The game’s own catch rules give an unseen throw a 1.5x multiplier, and the Aniipod you are holding multiplies on top of that. AniimoSync is throwing an Aniipod Track, which our data files rate at 2x.

One throw, one capture. His Aniipod count goes from 90 to 89 and the card comes up. That is the whole encounter, and it is why AniimoSync calls Thornblade one of the easier ones to catch.

The spawn rule on the card is the part to plan around: only one can appear at a time and it does not respawn. You get a single capture out of each spell of rain, and the next one is waiting in the same doorway when the weather turns again. That makes a second or third copy a question of how often you look at the map rather than of luck.

Pale Thorn, and what the catch actually unlocks

The capture drops an item called Pale Thorn and bumps two counters: Thornblade Special Form collection progress, and Collaboration Ability Level. The banner across the top of the screen says so in one line.

The rest of the item text is lore rather than mechanics, and it is unusually good lore. Among the Budsquire family, Thornblades are guardians armed with unbreakable thorns. One Budsquire brother became a Thornblade to protect his little sister, challenged one famed Lethal Thorn after another on the same pact each time, that the loser would break off their own thorn, and lost. Unable to be comforted by his sister, he ventured into a thunderstorm hoping to become a stronger Thunderstorm Thornblade. He failed. His sister, when her tears ran dry, began her own training and bloomed into a flower of grief on a stormy night. Pale Thorn is what she took from him.

Pale Thorn is not in the launch item table we hold, so it is a video-only find on our side, and we have no other source for what it is spent on yet. The two counters it moves are real, though, and the Forms screen prints the payoff for the collection half.

Thunderstorm Thornblade vs the Basic Form

Same stats, same trait, one extra skill and a second element. The Thunderstorm Form is not a straight upgrade, it is a different defensive body with a Lightning button attached.

	Basic Form	Thunderstorm Form
Elements	Grass	Grass plus Lightning
Role and stage	DPS, Nova Stage
Base stats	HP 96 · P.ATK 121 · M.ATK 53 · P.DEF 74 · M.DEF 73 · Haste 92
Trait	Sword Dance
Combat skills on screen	Three	Four, the extra one being Lightning Impact
Takes 1.6x or worse from	Dark, Fire, Wind	Dark at 2.56x, Fire and Ice at 1.6x
Takes 0.625x from	Grass, Earth, Water	Grass, Earth, Water, Lightning, Light
Where it spawns	Sea of Flowers, any weather	Sea of Flowers, rain or thunderstorm only

The matchup rows come from our element chart, which reads the multipliers straight out of the game’s data files, and a two element body multiplies its two defensive matchups together. That is what turns a bad Dark matchup into a very bad one: 1.6x twice over is 2.56x, so a Dark attacker hits the Thunderstorm Form for more than two and a half times normal damage. Against that, the Lightning half hands it two new resistances, to Lightning and to Light, and it pulls the Wind weakness back down to neutral.

Short version for squad building. The Thunderstorm Form is the better body against Wind, Lightning and Light opponents, and a much worse one against anything that throws Dark or Ice. Having both in the Aniilog is genuinely useful, and our Thornblade team page already runs the Thunderstorm Form as a situational variant squad rather than as the default.

One wording correction, and it is ours rather than his. AniimoSync calls the form grass and electric. The launch client calls that element Lightning, and so do we, so every reference on this page uses Lightning for the same thing.

Skills, trait, and the one skill the Basic Form does not have

Four combat skills, two innate skills and one trait. The fourth combat skill, Lightning Impact, is exclusive to this form, and the game says so on the tooltip.

It is the Lightning twin of Thorny Impact, identical in numbers and different in element. That matters because Grass and Lightning cover different things on offence: Grass hits Earth and Water hard, Lightning hits Water and Wind hard. The extra button is the form’s answer to a Wind opponent, which plain Thornblade simply does not have.

Skill	Tags	Might · EP · CD	What it does
Thorny Defense	Physical · Counter	75 · 20 · 6s	Enters a defensive stance that cuts damage taken by 20% and counters when attacked. Struck on the cast frame, it adds 30% Crit Rate for 15s
Thorny Rain	Physical · Combo	30 · 10 · 1s	Rapid thorn blade attacks, usable up to 3 times in a row
Thorny Impact	Physical · Dash · Damage Boost	57 · 20 · 1s	Thrusts toward the target. On hit, +15% Crit Rate for 15s
Lightning Impact	Lightning, form exclusive	57 · 20 · 1s	The same thrust in Lightning, with the same 15% Crit Rate for 15s. Only the Thunderstorm Form has it
Elegant Waltz	Innate · the ultimate	172 · 100 Ultimate · 8s	Repeatedly stabs a target with its thorn blade
ATK	Innate · Physical · Melee	6 · 0 · 0.1s	Wields the power of grass to attack targets at close range
Sword Dance	Trait	n/a	Each skill used grants 1 stack of Sword Dance, up to 4 stacks, lasting 15s. Each basic attack spends 1 stack to deal 180% extra damage

Every skill on that list breaks at 100%, which is unusual and worth knowing if you build around stagger. Read the trait and the three crit lines together and the kit argues for itself: three of the four combat skills either add Crit Rate or feed Sword Dance stacks, and every stack turns a basic attack into a 180% hit.

One small discrepancy to flag, because it is ours. The game’s data files list a fifth combat skill for this line, Aqua Defense, which does not appear on either loadout in the video. It most likely belongs to the Prismana Form, which is the Water bodied one, so treat the four skills above as what a Thunderstorm Thornblade actually brings.

Homeland worker abilities

Grass Level 3, Lightning Level 2 and Artisanship Level 3, at Habitability 100 and 120 Bud Tickets a day. Three jobs on one body, two of them at the top level.

Our data files carry two of those three. Thornblade is recorded with Grass Level 3 and Artisanship Level 3, which is what the Basic Form brings; the Lightning Level 2 line is the Thunderstorm Form’s own, added by its second element, and the video is the first place we have seen it. That is a real reason to prefer this form as a worker: a third job for free, on a creature you walk up to and catch.

For scale, Budsquire, the stage below, has Grass and Artisanship at Level 1. Evolving one is a large jump in Homeland output on its own. Our Homeland guide covers what each ability type unlocks and how Habitability and Bud Tickets feed the rest of the base.

Every Thornblade, and what Shining Thornblade means

Four forms, three of them caught in the wild and one drawn out by the Prismana system, plus a Shining egg that is an item rather than a form. If you searched for Thornblade without a form in mind, this is the table you wanted.

Form	Elements	Region	Spawn points	How you get one
Basic Form	Grass	Sea of Flowers	2	Catch it, any weather
Thunderstorm Form	Grass plus Lightning	Sea of Flowers	1	Catch it, only while the region is rainy or in a thunderstorm
Towerwood Form	Grass	Rosetower Woods	14	Catch it, any weather. Far the easiest Thornblade to find
Prismana Form	Grass plus Water	Sea of Flowers	1	The Prismana system, and one of the fourteen launch event Prismana claims
Shining Thornblade Egg	hatches a Basic Form	item, not a place	n/a	A Legendary egg. It will surely Hatch an Aniimo with Perfect Acquired Potential. The published route is the Custom Egg Box, DPS

So Shining is not a form. It is an egg rarity that guarantees the Potential rating, and the Thornblade it hatches is an ordinary Basic Form with the best possible roll. The Shining Thornblade Egg sits in our egg database with its own description, and the Custom Egg Box, DPS is the only published way to choose it: choose one of the following Eggs as a reward: Shining Thornblade Egg, Shining Scorchhowl Egg, or Shining Sherro Egg.

The family line is worth knowing too, because the stage below Thornblade is everywhere and the branch at the top is a real choice.

Budsquire is a Lumin stage Grass DPS with 117 spawn points across the Sea of Flowers and Rosetower Woods, and a Towerwood form of its own with 87 more. It evolves into either Thornblade or Melloblum, a Grass Support that heals rather than stabs. Catching a Thunderstorm Thornblade does not affect that branch at all: forms and evolutions are separate systems, and a weather form is a body you swap on, not a stage you reach.

Two more notes for completeness. Every Thornblade form except the Prismana one can roll an Umbral coat at about 1 in 3,000 encounters, and an Umbral is always Perfect Potential. And the four forms share one stat block exactly, so no form here is a numbers upgrade on another.

Is Thunderstorm Thornblade worth getting?

Yes, and the case is not about power. It costs one Aniipod and a walk, it hands the whole species a permanent +1.0% ATK through Form Research, it adds a third Homeland job, and it is the only Thornblade with a Lightning attack.

What it is not is a straight upgrade on the Basic Form. The stats are identical, the trait is identical, and the second element is a trade rather than a gift: Dark attackers go from bad to brutal at 2.56x, Ice goes from neutral to a weakness, and in exchange you get resistances to Lightning and Light and a softer Wind matchup. Pick the body for the fight, not out of habit.

Where Thornblade sits against the rest of the roster is a separate question, and our tier list has the ranking. For a squad to put it in, our Thornblade team page builds one around the Basic Form and keeps a Lightning flavoured variant for the Thunderstorm one. If this is your first weather form, read the Rainstorm Stellarys guide next: the method is identical and the creature is even easier to reach.

AniimoSync’s own verdict, and we agree with it: it is one of the easier ones to catch, the Sea of Flowers seems to be raining most of the time, and the form only asks for rain. On a creature this cheap to get, there is no reason not to have one.
