Same-Type Attack Bonus, usually shortened to STAB, is a hidden damage boost that applies when an Aniimo uses a skill that matches its own element. The game never mentions it in any menu or tutorial, but it is present and measurable in combat.
Quick answer: Yes. An Aniimo deals roughly 10% extra damage when the skill it uses shares an element with the Aniimo itself.
When STAB applies
The rule is simple. If the element of a skill matches one of the Aniimo’s own elements, the bonus triggers on that skill. If it does not match, the skill deals normal damage with no bonus.
This is the same mechanic that originated in the Pokémon series, carried over here without a label. Because Aniimo can carry two elements, the match check runs against either of them.
A clear comparison uses the two Pawney forms. Regular Pawney is a pure Dark type, while Snowfield Pawney is a dual Ice and Dark type. Both can use Weakening Smash, which is an Ice-element skill. Snowfield Pawney gets the bonus on that skill because its Ice typing matches the move. Regular Pawney does not, because it has no Ice element.
How much damage STAB adds
Direct testing with the two Pawney forms puts the bonus at around 10%. Both Pawneys were set to 409 ATK and attacked Alpha Ignitis, a target that is neutral to both Dark and Ice, so neither element gained or lost from a weakness or resistance.
The Ice skill (Weakening Smash on Snowfield Pawney, Weakening Slam on the comparison) was cast and the third hit’s damage was recorded. Snowfield Pawney’s Dark numbers were lined up against regular Pawney’s Dark numbers to cancel out any other difference, and the same adjustment was then applied to the Ice numbers. The remaining gap in Ice damage came out to roughly 10%.
| Aniimo | Dark DMG | Ice DMG | Adjusted Ice |
|---|---|---|---|
 Pawney (Dark) | 1280 | 1164 | 1164 |
| Snowfield Pawney (Ice/Dark) | 1240 | 1240 | 1280 |
| Difference | — | — | ~10% |
Some wider estimates place the bonus closer to 15–25%. The controlled Pawney test is the more reliable figure, so plan around a boost in the neighborhood of 10% rather than a larger swing.
Why dual-element Aniimo gain the most
Dual-type Aniimo get the clearest edge from this bonus because their kits often include a skill from a second element. When that skill matches their secondary typing, it picks up STAB on top of its normal output.
Base Fulmintis is a good example. Its innate element is Lightning, yet it carries a Light-type skill. A single-element Aniimo would get no bonus on an off-element skill like that, but a form with the matching second element does.
A second element is not purely an upside. Weaknesses and resistances stack across both elements, so a dual-type Aniimo can take far more damage from a counter element. Prismana Fulmintis, with combined Lightning and Light, takes about 2.5x damage from Dark, more than its base form. The STAB gain is worth weighing against that defensive trade.
How to use STAB in practice
Check each Aniimo’s element against the elements of the skills it runs. Favor skills whose element matches the Aniimo for a small but consistent damage increase across the fight.
- A skill matching the Aniimo’s element gains the bonus.
- A dual-type Aniimo gets the bonus from either of its two elements.
- An off-element skill deals normal damage with no bonus.
- The bonus is separate from type advantage, so it stacks with hitting a target’s weakness.
Because the boost stacks on top of elemental matchups, the biggest numbers come from an Aniimo using its own element against a target that is weak to it. Line those two factors up and the matching skill carries both the type multiplier and the roughly 10% STAB bonus at once.
