Itherael's basic attacks grant him a stack of
Uncertain Time, increasing his movement and attack speeds by 5% per stack.
Attacking with 4 stacks of
Uncertain Time also causes Itherael to phase through the target the attack hits, dealing 75% increased damage and removing all stacks of
Uncertain Time, as Itherael moves through the target in a straight line.
Itherael loses a stack of
Uncertain Time every 5 seconds spent without gaining one or dealing damage to a Hero.
And the ults seem OP, but I'm **** at balancing.
Maybe lean more into his archetype of time alteration, fate theme (stacking up to inevitable doom) and give him a support ability?
Make him melee Chromie, with some Tyrael support and Malth stickiness (?).
