Bustling Fungus (Risk of Rain 2)

Not to be confused with the first games version, the Bustling Fungus.

Bustling Fungus is a returning common item in Risk of Rain 2. Remaining mostly unchanged from its first iteration, this item heals the carrier and any friendly units nearby for 4.5% of their max health per second. This time around, however, stacking the item will increase healing for only 2.25% per stack, as well as adding 1.5 meters to the range. Aiming and using abilities is allowed, as long as they don't move the character.

Visually this item appears as a green cluster of fungi on the players right shoulder.

Since the Engineers Auto-Turrets can't move, their fungi will be active until they are broken. Placing the turrets withing each others healing range will allow for them to heal one another. Any player in this overlapping zone will be healed by them both. The fungus can also be seen on the turret.
