Elemental wave skill twice

I didn't see it documented and as of right now I'm not sure how I have been doing it, but there are certain situations where you can use elemental wave twice

Ie: after using elemental freeze, I can use elemental life drain immediately after... Has this happened to anyone else? Is this a glitch? (I can't recall if a monster hit me during the times this has occurred) or is there a percent chance this can happen based on rank?

To be able to do it twice is definitely a glitch. I'll look into this, but until then, refrain from adding anymore information as I bring this up with the staff.

The Elemental Wave skill triggering twice is the same reason heat buster triggers twice. If you get hit in the middle of the skill, you can use it again. Say before if you got hit in the middle of heat buster, you can trigger it again, same with elemental wave heat buster you, same with elemental wave frozen blast, and elemental wave life drain.

I guess that makes more sense.
