So I've been looking around on the net, and found something interesting. Miraak's Robes are actually somewhat useful. Not only can they activate several times a second if hit by certain spells, but they can apparently activate via your own spells, as well.

That said, does anyone know of a good way to forcably proc the explosion effect on Miraak's Robes? I'm thinking a potion with negative effects might do something, but I'd like to hear other methods as well.
