Events and Trash Mobs in Fungal Folly
Keep in mind that in some cases, there might be a different event, which will consist of having to do 5 unique challenges from each of the trapped ancestors around the map. For the guide's sake, we have included the most commonEvent #1, the Scout rescue mission.
Event #1 — 0/10 Scouts rescued
You have to clear all non-boss-enemies around each of the scouts before rescuing them simply because you will not be able to do so while being attacked. Here are all the trash mobs you must pay attention to:
Trash Mobs in this Area
- Interrupt Fungal Rotspreader's
Rotten Bolt.
- Out-range the Infected Beast's explosion (they will start channeling it at around 25-30% HP).
- Stop the
Battle Roar cast coming from Fungal Gutter, as it will buff the Haste of all nearby enemies by 25%. In addition, side-step their
Vicious Stabs frontal.
- Avoid the
Infectious Spores ground effect from Fungal Rotcaster, while using your stops for
Rotten Bolt.
Spinshroom Boss Guide

- Out-range the
Fungalstorm channel and avoid the ground-swirlies.
- Once Spinshroom finishes its
Fungalstorm channel, it will become
Dizzy, becoming stunned for 8 sec while taking 50% increased damage.
- Sidestep the
Fungal Charge.
- Get away from any existing ground-swirlies before the
Fungsplosion cast has been finished.
