Just a random suggestion, feel free to leave feedback.
Revenants start at 100 Energy.
Legend Swap restores 100 Energy and removes Upkeep.
Skill Energy cost removed.
Each skill cast will +1 ~ +3 Upkeep.
Healing skill adds no Upkeep.
Can keep casting weapon skills or utility skills as long as they are off cooldown, but will keep stacking Upkeep which will drain Energy over time.
Previous Upkeep skills will be changed to consume 1 Energy per second up to 3 Energy per second based on how long it has been active.
So basically the Revenant can keep using skills as cooldowns allow, but instead of totally deleting yur Energy, it will stack up the drain per second to the point yur Energy Bar just flatlines and require a Legend Swap to refresh.
If th Energy bar flatlines, all Upkeep is removed and start to regenerate Energy rapidly.
Can be traited to regenerate faster if the Energy is drained in this manner.
If I play a stupid build, I deserve to die.
If I beat people on a stupid build, I deserve to get away with it.
