As horrible as Dark Ascent is right now, it’s simply too predictable (easy to dodge) and does not do that much damage and utility compared to the other heart runes. But a good easy fix would turn it into a flying dash that travels about the distance of a great axe charge. Similar to how Isabella attacks us in Tempest Heart, by flying high and dashing low, but with a quicker animation for players. The stone wall is a good cc and dmg negate ability, overall really good for squishes, but dark ascent could be for players who need more mobility to evade attacks or engage in a quick entrance as they damage players they pass through.
Please let the devs hear this and give this heart rune of a joke some real love and attention.
PS: Cannon is whack, no idea how to fix this
