Evo Princess
Overview
“This stunning Princess shoots flaming arrows from long range. If you're feeling warm feelings towards her, it's probably because you're on fire.”
Ability
Evo Princess's first shot and every third shot after fires an icy arrow that slows nearby enemies by 50% for 1.5 seconds. When she is defeated, her remaining arrows drop to the ground, creating an area of ice that slows enemy troops passing through it for 3 seconds.
