Brand new to D&D 5th Ed. Here I am trying to wrap my head around the rules. The very first enemies you face, Imps, and the Gith is hitting for less then 4 DAM with a STR of 17.

How does that possibly happen?! I'm super confused.

Oh, turns out they have slashing resistance. (Figured that out on my second playthrough.)

Yeah, maybe don't do that.
