I'm going to be running a small adventure for some friends based around the idea of clearing out a keep that is currently infested with Goblins - I've got some goblin dogs and dire rats and usual type goblins, but I wanted some of the box goblins to be classed
the players will be level one and there are 4, so a standard encounter would be CR1
I've created a level one sorcerer, which according to the core rule book has a CR rating of 1/2 and an exp award of 200. To take this up to a CR1 encounter I would either need to make the sorcerer a level 2 or would add some additional beasties like an additional goblin or two - each 1/3 CR or 135 exp.
if I wanted to make it a tough encounter (CR2) I could make the sorcerer level 2 (effective CR 1) and still add 2 extra goblins
is that correct?
