Core effect · what sets it apart
Equipped Aniimo gain 0.7 additional P.DEF and M.DEF per level.
How held items work →What the Giant Tortoise Shell is for
The Core effect adds 0.7 P.DEF and 0.7 M.DEF for each level, on top of an HP Base effect, both cut from 0.8 at launch. Nothing here raises damage: it is the defensive counterpart to the Fang and the Horn, for an Aniimo you want standing rather than hitting.
The Giant Tortoise Shell in numbers
The Core effect is 0.7 P.DEF and M.DEF a level and nothing else, so the only question it raises is the level at which it clears the 15-point threshold the 15 energy line pays out on.
22
Level at which the Core effect alone passes 15 P.DEF and M.DEF
0.7 a level, so 15 points are passed at level 22: 15 ÷ 0.7 = 21.4.
19
Level at which it passes 15 with the 10 energy line's +2
The 10 energy line adds a flat 2, so the Core effect only has to find 13: 13 ÷ 0.7 = 18.6.
The 15-point threshold reads the Aniimo's P.DEF and M.DEF, which the item is only one contributor to. The levels above are where the item's own contribution clears it on its own; an Aniimo already carrying P.DEF and M.DEF from elsewhere clears it sooner.
The Giant Tortoise Shell at each rarity
| Rarity | CP | Base effect | 10 energy | 15 energy |
|---|---|---|---|---|
| 50 | – | – | ||
| 100 | M.DEF Potential +2, P.DEF Potential +2. | – | ||
| 200 | M.DEF Potential +2, P.DEF Potential +2. | DMG Reduction +10%. If P.DEF Potential exceeds 15, gains an additional 5% Physical DMG Reduction. If M.DEF Potential exceeds 15, gains an additional 5% Magic DMG Reduction. |
What is unusual about the Giant Tortoise Shell
A flat stat for every level
4 of the 24 Core effects are written this way, with no condition to meet and no resource to hold. They are the same item in four stats, and the choice between them is which stat the Aniimo needs.
The Minespine drop table
Minespine is the only Alpha Aniimo listed as dropping the Giant Tortoise Shell, and it drops 2 other held items.

Which Aniimo carries the Giant Tortoise Shell
Aniidex →No in-game recommended build names it, so there is nobody to list. Its Base effect points it at Aniimo built to stay standing.
Closest rivals for the HP slot
All 7 →| Item | Core effect | Builds |
|---|---|---|
| Grants a shield equal to 4% of max HP for 5s after taking damage 10 times. | 0 | |
| Continuously deals Lightning damage equal to 2% of max HP to enemies within 3 meters. | 0 | |
| Restores 1.4% HP for every 10 meters moved. | 0 |
All 7 grant +10% HP at Legendary, so only the Core effect separates them. These are the 3 the in-game builds pick most often; the other 3 are on the hub.
