I do have the damage values on COre COliseum, however.
The centipede used its acid breath weapon for 23 damage. I can't remember who saved and who didn't. Aureus didn't have to since she was on the other side of the bridge. I do remember that. I don't think Quinn saved. The centipede bit Lorien for 14 damage and 9 total points of Dexterity damage (he natural healed one point with rest). I think I had Caerth cast lesser restoration on the bard, but I can't remember. I'll see if it's in my dice rolls.
The centipede also bit Quinn for 19 damage. He didn't suffer any Dex damage so he obviously made his save.
