That is such a fun name to say, Abishai. I am working on converting them over to 5th edition and trying to decide should i stat them out as i would a race or as a monster. Im thinking right now the later but what challenge rating would they be? Or rather what level party should they be challenges for?
Im not intimately familiar with 2nd edition so im not sure what these relative strengths would convert to. Was thinking a red abishai would convert to like 5th or 6th level CR. Green being like 2nd or 3rd? I have a copy of the DMG so i have some guidelines on how to assemble their stats once i have an idea of how strong these guys should be.
