Bustling Fungus

The Bustling Fungus is a returning item in Risk of Rain 2. It creates a green bubble which heals players for 4.5% health every second after the user stands still for 2 or more seconds. Both the radius and healing amount can be increased by stacking, with no effective limit on radius or health restored.

Having 44 Bustling Fungus will reach more than 100% healing, which is effectively a soft cap without items using overhealing such as Aegis.

This item is extremely powerful to stack as Engineer, due to his turrets' ability to inherit his item inventory and their immobility making the healing bubble persist wherever the turret is placed.

The healing dispensed scales with the max health of the recipient. It can affect NPCs, such as Drones, Aurelionite, or even Squid Turrets. Due to this, it can be used to keep multiple turrets alive despite their constant health drain, as well as having many other synergies with minion items.
