Card mentions damage without specifying what kind, so any kind works. Note life payment doesn't count, though some costs are worded as "take 1 damage" and would activate this. It also doesn't specify what monster you're allowed to destroy on the opponent's field, so any there can be chosen.

Just to note two things, however: you must take damage. If it gets reduced to 0, it won't activate (like with say, White Dragon Shield) and as long as your life is at 6 or less after the damage is done, it'll activate. I'm glad the show clarified that bit, though annoyed that it made it better (Gao was at 7 and was reduced to 6 and Drum destroyed a monster).
