Sorry for the double post, but I just wanted to add that I'd welcome any suggestions for a permanent solution for the disintegrated PC. The player would like to get the character back, and I'd like to work with her on this. (This is for my DDAL season 4 Ravenloft campaign.)
The other PCs will gather up the magic items (and presumably the dust)
Aha. Makes sense, I guess. The beholder does have a few wonky effects (like the petrification ray having a Dex save rather than a Con save).
Yes, but then once it hits you and you become restrained, you have to make another Dex save to avoid becoming fully petrified, which doesn’t make sense. At that point, you’re not trying to dodge, you’re trying to resist.I think the idea is you can dodge it.
Also, if it’s Dex because you’re trying to dodge, then all of the rays ought to require a Dex save to dodge.
It's incredibly hard to damage a PC's stuff in this edition.
