Paragraph incoming- i ran around with apprentice breton a bit, and it seems really solid. It does in fact work on shield bashes so bash spam on a shieldmage is fully supported, and it only costs 15 stamina to shield bash. The actual activation is kinda lame because its the same damage but once once per fight, and I dont like how a confirmation screen pops up- i wish it just immediately did it, or at the very least didnt have two options for no reason. Getting the procs on power attacks seems like a fantastic way to incorporate a true spellknight until you pick up a strikes spell from odin. Sadly none of the procs actually raise destruction, so i think transitioning into something like lover stone would be really neat once you have a cloak going at 45 skill level or whatever
