Is there a way to avoid sustaining any knockback?
Is there any way to mitigate knock-back taken so you do not move at all? I would like to not be moved at all whenever taking damage, in specific regards to how Bustling Fungus works.
There is no item in Risk of Rain 2 that reduces or affects knockback directly in any way.
However, if you don't take damage then you can't be knocked back, so taking a few stacks of Tougher Times might help to mitigate knockback a little bit since you'll be blocking some hits, and therefore not being knocked back by them.
