Exactly like Dark Imbue, Ice Point Greaves do a flat 10 resistable physical damage on hit that triggers resistances.

I suggest changing it to 10% Ice ATK per rank, but have it split the damage for Rapid Kick, similar to Phoenix Talon.

It'd be neat if this applied to basic attacks too, if it doesn't already.

However I do like the OP's idea the most here.

That'd probably be fine too, as long as it also split for multiple attacks (mutated gun).
