So, in addition to what the armor can do to remove AC, I think I'll give each suit its own ability based on appearance...<br/><br/>For Diomeera, the full armor has a long skirt in the back (can't see it in that picture, but I found a few other ones of her), so one of the abilities is a trip attack against her.  Likely a limit of one per encounter or a few times a day.  For Lissandra, I'd like to do something with the "claws" on the armor, though I'm not quite sure what; perhaps attempt to grapple her.<br/><br/>As an aside, Wild Shape kind of messes with how the armor works, but I'm not sure what exactly to do to keep it from breaking something.  Thoughts?
