Aave
Aave (also known as Spirit) is a group of enemies that apply a status effect to nearby creatures, including the player. They have no method of directly attacking, and serve only to cause mayhem with the effects that they apply.
There are four spirits:
- Viha-Aave (also known as Anger Spirit), which applies
バーサーク - Utu-Aave (also known as Fog Spirit), which applies
混乱状態 - Neva-Aave (also known as Bog Spirit), which applies
スライミー - Kaamo-Aave (also known as Depression Spirit) which applies
しなびた.
Besides the different effects that they apply, they are functionally identical. They leave no corpse upon death.
行動
They tend to actively follow the player around when they have line of sight. They are not hard targets to dispatch, but their status effects can occasionally help the player; Neva-Aave's slime will douse you if you are 
オンファイヤー (but will not prevent you from catching on fire to begin with), and Utu-Aave's confusion can cause enemies to have a tough time getting close.
Amusingly, the spirits will even apply their effects to destructible environmental objects such as Propane Tanks. Besides the しなびた status, this has no effect. Kaamo-Aave can be considered the most dangerous of the spirits, as the しなびた effect will cause creatures to take 10x damage from most sources.
トリビア
- The spirits are affectionately named by the community (in order) Harry, Jerry, Larry, and Garry.
