Strategy
Kainin’s trait can grant a large amount of bonus damage to her abilities. She can use positioning, Ability 1’s Slow, her ultimate ability’s knockback, and displacement from Ability 2 to trigger her trait multiple times to deal a lot of damage to the target. She can also nimbly enter battles with her Ability 3.
