I just found out last night that I may have a 6th player in my group. Originally I was going to stay with 20 point buy and maybe add (smaller)creature in each combat.
But having 6 now, what do you recommend on adding to make it more challenging? Should I lower it to 15 point buy? The only thing is with the 6th player, I don't know how consistent she will be on making it to the sessions. I don't want to make it 15 point buy and then have it hurt them when she isn't available.
For the first goblin encounters, I am thinking adding a couple of base goblins in the first one, maybe an additional Warchanter for the second and debating on an extra goblin commando for the third. What do you think?
And is there some kind of rough formula I can use to determine on what should be added?
