Cabled said:Yeah, I'd likely allow it provided it happened within a couple minutes of drinking the holy water. Because honestly, why not? It's not going to turn the character into some kind of living holy water fire hose, I would probably allow it to do a vial's worth of holy water damage plus a vial's worth of acid damage...that's roughly the damage potential of a greataxe, one use only. It's the kind of thing the players will probably remember for years. It's a decent way to sneak a shot of holy water into the domain of an intelligent undead of you planto open with the "parlay then ambush" tactic.
And given where many undead live and the form they take, it might be easier to throw up than you think. Heck, carry a vial of epicac or some similar herb around for the purpose of it. By the time you set it all up just to do it, the extra effect would probably not be viewed as worth the extra effort.
why not would be because the type of player who comes up with this "tactic" in the first place likely would try it whenever he faced an undead again. Or simply vomitting on any other opponent to sneak a shot of acid damge in on the BBEG. It opens up too many attempts at leveraging the rules.
Adding in an epicac type herb would even further taint said holy water, and as has been already stated several times, you do not vomit up enough acid to do a measureable ammount of damage.
