I have a party made up of four level twelve characters. I am trying to build an encounter that won't kill them but come close. The encounter is:
2 Sellswords
6 Highwaymen
3 Battle Mages
All of which are from the Gamemastery NPC gallery. This should be an encounter CR13, but if my math is wrong this might be off. Should I include the CR equivalencies for building encounters with more then one monster/NPC or should this encounter stand as is?
