This was my first foray into Southern Swamp, and its annoying nagas that weaken me.
After I managed level 2, however, I ran across a level 1 naga that the combat predictor says will not damage me. I do not have first strike, so I don't understand why I will kill him, but he won't touch me.

Also, does weakness ever expire? Or it's permanent for that dungeon?
