combat: Players always go first, actions resolved in post order.
I will list enemy AC and HP so you know if it hits and kills.
I don't do maps but for things like hide or aoo range I'll make clear notes of that stuff each round.

be proactive
1. games die bc players are waiting on other players to post. Kindness kills games; don't worry about being a jerk! Post often!!!! This keeps me excited and I'll post more often too!
2. this also means don't wait for me to ask you to roll something. If you feel like a perception check, roll it and post it and I'll respond to it, even if it's just to say there's nothing interesting.

potions
it takes a full action to properly drink a potion: for health that means you get FULL HP
BUT
you can use a bonus action to quickly chug a potion: meaning you roll for HP, or if it's any other effect, roll a d20, 10 or higher you get the full benefit, 9 or lower: wild magic table

NAT 1
It is up to you if you punish a nat 1. Here's a table for the brave and bold:

MULLIGANS
If you roll 3 fails in a row (combination of saves, checks or attacks) your next roll (or whenever you choose) is an auto nat 20 (use this wisely, I once had someone save it for their death save).
