Flesh - I thought it was a 10d6 wand, and didn't think of sneak attack. If you want the numbers to be correct, roll them yourself.
Salth - I just don't see the air bubble protecting from acid.. as far as I'm concerned the 'gas' portion of the breath weapon is flavour text, not something meant to make it easier to defend against than every other breath weapon. It's acid, not poison.
Myth - As Shayuri pointed out IC, evasion doesn't work like that.
Here's a breakdown of reflex save/evasion interaction
Normal: Failed save = Full damage, Success = Half damage.
Evasion: Failed save = Full damage, Success = NO damage.
Improved Evasion: Failed save = Half damage, Success = NO damage.
The ring provides Evasion, not Improved Evasion.
Secondly, there's never a case of decimals in D&D math. You always round down unless otherwise stated, so half of
55(Not 45 as you stated in your post) would be 27. But since you failed and don't have IMPROVED Evasion, you take the full 55.
Rathan - You point it out with your reflex save, but your acid resistance should be included in your combat statblock with your other resistances. This is the last round I'll be making exceptions for people, from now on if it's not in your statblock you don't benefit from it.
I know it's asking for you guys to keep reprinting a lot of stuff, but with over a half dozen high level PC's, it's the only way to maintain my sanity while DMing.
Shayuri -
Actually, the ability to threaten while grappled and the ability to grapple multiple creatures are both available to creatures with the Improved Grab special ability who use it to act as though not grappled. Such as this 'Drow/bear/whatever'. (Note also that most bears DO have improved grab, so even if this were just a normal bear, it could do that).
Also, you haven't included any combat info in your last few posts. I am double checking people's character sheets, but after this round if I don't see your resistances/immunities and you guys don't have them listed in your combat posts, you won't benefit from them. It would also be nice to know how many HP each PC has left.
