Nice, but since there was no message of MB on the spell itself I would guess it's more like the code to assign that RoE is oversimplified and doesn't check actual magic bursts, only something like "casts on the same target (yourself) that is receiving a skillchain effect). I wonder if there's a spell you can cast n yourself that would show an MB message, maybe cure since you could in theory burst it on light on an undead for damage..
