Way of Dark
Undieing - Resurrect with 1 heart every time you die, unless you are the last defeated opponent.
As long as there is action happening on the battlefield, you will rise again. Smart opponents will then target your allies. So make sure you make your second chances count. For a secondary ability, consider a support ability like Croon if you're in a team. Respawning moves you to a random location, so a reliable damaging projectile is really the best pair with Undieing.
