In #Pathfinder1e #Ustalav tonight, the level 3 party knew they were going to the ratfolk warren to fight invasive giant black widow #spiders. They used four scrolls of delay poison and took anti-venom along for everyone.
The giant black widows were squeezing (-4 attack, -4 AC) in the narrow warren tunnels and didn't even score a hit on the party as they were mopped up.
Oh well, the ratfolk community will still pay them on the agreed terms.
