As a guess, 1/3. It's between 1/2, which seems to be the "0" in these cases, and 1/4, which is already established as the "-2" by the kobold warrior in the MM/SRD. It is also the CR of the 1st level goblin (-2 NPC class CR) warrior in the MM/SRD.Darklone said:Sooo... what CR do you have to use for a warrior 2 kobold?
1/4, as the 1st level warrior in the MM/SRD.Darklone said:Or adept 1?
olshanski said:I think of -3 as being 3 steps away from 1:
a level 1 NPC kobold = 1/4
a level 2 NPC kobold = 1/2
a level 3 Npc kobold = 1
a level 4 Npc kobold = 2
etc.
perhaps I am wrong, but this is how I've played it.
