Here's how I think the skill can be good, in 2 points

-At 15 ki it should buff the damage of the skill by Ki%
-At 25 Ki it should Knock enemies back 5 tiles.

Also, maybe if Ki Awoken is active it has some special interaction, like doubling range or destroying all tiles.

And maybe Suppress Ki can only consume up to 15 Ki, disabling any effects beyond that.
