I put the potions on my sheet in the other thread to make sure they were tracked somewhere. I had some questions about the armor. 5e doesn't have an immediate action, and I'm not sure what that would translate to; 5e doesn't have an action that's valid even during an opponent's turn, except maybe a free action. Bonus action seems closest, maybe just an object interaction. And Matthan mentioned it, but there's no Ghost Sound, but Minor Illusion is basically the same thing without the "number of humans worth of sound per caster level" faff, plus images, so just saying "the sound functions of Minor Illusion" would be pretty close.
Also, when you say "antidote," is that meant to be the Antitoxin from the PHB (gives advantage on saves vs poison for an hour), or a different thing?
