Häivehiisi

The Stealth Hiisi (in-game name Häivehiisi) is a Hiisi most commonly roaming the Fungal Caverns. He will follow and shoot both players and enemies with an invisibility charge.

Behaviour
The Häivehiisi cannot actually hurt you, but will attempt to turn everyone near him invisible, making it harder for the player to spot incoming enemies. As being stained with a liquid will prevent invisibility from triggering, he can often be spotted continuously shooting the same creature over and over with no effect.

Combat Tips

 * Observe that some flying enemies can still be fairly easily spotted even when invisible due to their animated tentacles still being shown.
