Toveri

Friend (in-game name Toveri) is a secret enemy.

Location
It can be found in the Friends' Room, which is generated in one of 6 random locations, and is most easily found with the Spatial Awareness perk, which highlights the room's location with a green square.

Behaviour
It will follow the player while spitting seeds, and performing a melee kick once you get close enough.

However once you kill at least one Kauhuhirviö, it will become a hostile miniboss attacking with a fast blue projectile. With every consecutive kill it will become exponentially stronger, increasing it's HP, firing rate and immunities.

For every Kauhuhirviö killed, its HP will be multiplied by 1.5, take 0.1x less damage from Projectile and Slice sources, and reduce its firing delay by 1 frame, maxing out at 9 kills.

When at least 1 has been killed, it'll gain immunity to Melee, suffocation, polymorph, fire, explosions, Touch Of spells, both Freezing and Electric stuns, and Curse damage.
