Sheet OGL 5e, Mac, LInux and Windows in Firefox. When dragging and dropping a monster it creates to values in the sheet npc_ac and ac. why are these different. Example below of a Lich. I have tried others with the same results. Craven
I believe this is because the ac attribute is the calculated ac value for PCs (i.e 10+dexterity_mod if no armor is found in the character's items). A lich has a +3 dexterity mod according to the MM which explains the 13, while the statblock shows them having a natural armor of 17. I also recall the ac attribute being one of the few attributes that is always calculated regardless of whether the character is a PC or a NPC.
