ToME: the Tales of Maj'Eyal

does the Auto attack procc from Corrupted Strength procc just for normal Spells or are the "melee Spells" included like Rend for example. sry if its a dumb question.

Activating any non-instant (and non-sustain?) talent labeled "spell" counts. So, for example, the melee spell Acid Strike absolutely counts, but, say, Flurry (under Dual Techniques) does not because it's not a spell.

I may be missing it, but I'm not seeing any spell named "Rend".

Probably worth to mention Channel Staff which counts as a spell too, making Staff Reaver even stronger.
