And just in case someone wants to check my math when I'm saying there's a 65% hit chance:

Typical "white room" PC has a 16 in their attacking stat, and starts with a +2 proficiency bonus, so they have a +5 to hit. Baseline AC for a CR 1 creature is 13. +5 vs 13 means you hit on a 3 or higher. That's a 65% hit chance.
