While I do find the idea of many moves (and now styles!) having alternate uses, it may make them too powerful if you can use them all in the same fight. An example would be your sword can bleed the enemy or have piercing, well first you bleed them then switch to the piercing. You’re not having to choose one or another like the ki channel idea. Of course, if that is all part of a fighting style rework, that might just be one of the perks, but if that was just a regular move learned from master that’s probably too much.
This is actually something I’m really liking about alternate uses for ki channel, you can only pick one, and because ki channel is such an impactful move it could really make things interesting when one player chooses one of the alternate versions. I could even see something like in the example where a damage boost would want to be used early in a fight, but ki channel normally wants to be used late (and often, when used correctly near end of fight, the first person to channel loses).
