Our session report is here.
For anyone wondering how we dealt with the drinking competition we had Vipin and the dwarf make Constition (Poison) saves, starting with a DC of 15 and increasing by 1 each round. Failing 3 rounds would result in passing out drunk.
Tanis was using Guidance to give Vipin a bonus on his save and I had him make DC15 Dexterity (Stealth) checks to hide his casting (which he annoyingly passed each time).
Next session while still under the effects of the alcohol Vipin will have a sense of being "invulnerable" while having disadvantage on any dextrous tasks until he can sleep it off.
Next week I'm going to have Stokely approach the "pub champion" with a request to investigate missing miners which will hopefully lead to a zombie infested dungeon crawl through dangerous dwarven mines.
