What it does.

Bustling Fungus
Common item (white)

Stand still for a second and a circle appears that heals you and allies inside. Each extra fungus makes it bigger and heal more.

Game text: «After standing still for 1 second, create a zone that heals for 4.5% (+2.25% per stack) of your health every second to all allies within 3m (+1.5m per stack).»

Stacking: Each copy adds the same, no cap.

Watch out: It heals based on the health of whoever is inside, turrets and drones too. Some skills push you slightly and break the circle.

It has a void version: Weeping Fungus. Pick that up and every copy of this item turns into it.
