Not quite. You're thinking of their CR, not their ECL.calypso15 said:Hmm... fair points. Is there a reasonable way to convert them? For example, using the "Improving Monster" table, you can convert 2 dragon or outsider HD to 1 class level, or 3 animal, magical beast, or monstrous humanoid, or 4 aberration, construct, elemental, fey, giant, humanoid, ooze, plant, undead, or vermin? (Not that I expect to see many vermin PCs).
