How held items work →What the Fission Needles is for
The Core effect pays out on basic attacks: each one has a 50% chance to deal double damage. It is tied to the basic attack rather than to a skill, so it wants an Aniimo that spends real time attacking rather than one built around a single skill window.
The Fission Needles in numbers
The Core effect is a coin flip on the basic attack and nothing else, so it reduces to one multiplier on basic attack damage.
×1.50
Basic attack damage, averaged over the flip
A 50% chance of double damage: 0.50 × 1 + 0.50 × 2.
0.50 EP
EP per basic attack at 10 energy
1 EP on a 50% trigger: 0.5 × 1.
The 15 energy line adds 30% basic attack Damage Amp for 10 seconds, but only while EP is full. How often that is true depends on the Aniimo's spending rather than on the item, so it is not folded into the multiplier above.
The Fission Needles at each rarity
| Rarity | CP | Base effect | 10 energy | 15 energy |
|---|---|---|---|---|
| Rare | 50 | Damage Amp +3% | – | – |
| Epic | 100 | Damage Amp +5% | Restores 1 EP when triggered. | – |
| Legendary | 200 | Damage Amp +10% | Restores 1 EP when triggered. | If EP is full, increases basic attack Damage Amp by 30% for 10s. |
What is unusual about the Fission Needles
Irisal and the Forsaken Held Item Pack
The same 3 held items sit behind both: Irisal is the only Alpha listed as dropping the Fission Needles, and the Forsaken Held Item Pack rolls one of the same 3 at a random rarity.

Closest rivals for the Damage Amp slot
All 11 →| Item | Core effect | Builds |
|---|---|---|
 Ferocious Fang | Equipped Aniimo gain 0.7 additional ATK per level. | 34 |

 Ambusher’s Cloak | Damage Amp +25% for attacks in stealth or from behind. | 0 |
All 11 grant +10% Damage Amp at Legendary, so only the Core effect separates them. These are the 3 the in-game builds pick most often; the other 7 are on the hub.
