## Return and Frustration deal no damage when the user's happiness is low or high, respectively
|
||||
|
||||
This happens because the user's happiness (or 255 − happiness for Frustration) is multiplied by 10 and divided by 25, which rounds down to zero when the happiness is 0–2 (or 253–255 for Frustration).
|
||||
|
||||
**Fix:**
|
||||
|
||||
Edit [engine/battle/move_effects/return.asm](https://github.com/pret/pokecrystal/blob/master/engine/battle/move_effects/return.asm):
|
||||
|
||||
```diff
|
||||
BattleCommand_HappinessPower:
|
||||
...
|
||||
call Multiply
|
||||
ld a, 25
|
||||
ldh [hDivisor], a

|
||||
ld d, a
|
||||
pop bc
|
||||
ret
|
||||
```
|
||||
|
||||
And edit [engine/battle/move_effects/frustration.asm](https://github.com/pret/pokecrystal/blob/master/engine/battle/move_effects/frustration.asm):

```

### Dragon Scale, not Dragon Fang, boosts Dragon-type moves
|
||||
|
||||
**Fix:** Edit `ItemAttributes` in [data/items/attributes.asm](https://github.com/pret/pokecrystal/blob/master/data/items/attributes.asm):
