it's been mentioned that he "gains stacking power" from casts up to three casts, then resets.

I imagine it's probably a percentage damage boost to his abilities ie one cast charge = +10% damage, second = 20% etc. In addition, it appeared that his coffin opened up each time he gained a charge; maybe he starts with bonus armor/mr and loses it as he gains charges, making him more powerful but more susceptible to damage.
