Pretty fun character. Though I only know basic combos with the character (like the choke-the-enemy-out and kicky thingy while in diamond form). So, if you have any tips, please tell me!
Use your E ability to kill dive characters. The health of the sentience is determined by the current health of the target, and most dive duelists have 250-300 health.
The sentience automatically disappears when the target steps out of a certain range, so use it primarily when they are distracted with fighting your team.
