Her skills are noisy, and good evie always take the risk to come near you when u hear some blink/soar sounds be ready for the fight. always know this she might be faster than you but not better damage dealer
If an Evie is coming after you solo, gather around with enemies to avoid being out-flanked. Also, expect an Evie after ice-block to teleport immediately.
If you know that youre weapon is going to hit an enemy, use ice block. Becuase there's a chance that you will die before your bullet fire will hit the enemy. (Only use it when you think and know that its going to hit them)
If going for a surprise attack or finishing off an enemy, the best tip is to blink in the air. And when youre close to your enemy FIRE. Doing this makes it easier to hit people
A good is Evie is good at dodging incoming fire. Always predict your enemies's moves. If you know that kinessa is going to fire her shot, Blink or Ice block. Same goes for shalin, cassie (after dodge roll), grover and others
