Wisp
From SpiralKnights
Wisps are a type of monster found in the Clockworks. They do not deal any damage, but cause status effects.
Traits
Wisps are considered a Drone monster, and thus follow a set path and do not target players. They also drop nothing other than hearts and Vitapods.
Types
Strategy
With the exception of Golden Wisps, Wisps that are destroyed have a chance of dropping hearts and a smaller chance of dropping Vitapods. When you clear out an area and are low on health, it's best to head back to a previous area which contain Wisps, and destroy them to obtain some health.
