Oh a Duergar, wasn't aware they had advantage on saving throws.
In that case you could also eat any rotten food; it gets you poisoned by default and gives you disadvantage on all checks. Rotten food is how I intentionally fail a certain persuasion dialogue check in Grymforge, so I can legitimately provoke the Duergar slavers to attack me.
Uhhh brilliant tip. I'll try that on Nettie later. It's always hard to get three medicine check fails in a row, but if I do, I'll have the best reason for my self-defense to kill her.
