Let's see... without RHD or spell-likes or specials, a half fiend would receive:<br/><br/>Outsider type (immunity to charm/hold person)<br/>Fly speed=land speed.<br/>+1 Nat armor<br/>Claws and bite<br/>Poison immunity, Resist 10 fire, cold, acid, and electric<br/>DR 5/magic<br/>SR 10+HD<br/>+4 Str, Dex, Int and +2 Con and Cha<br/><br/>To compare to the +2LA drow...<br/>+2 Int and Cha<br/>SR 11+HD<br/>+2 Will<br/>1/day 3 1st or 2nd level spells<br/>Light Blindness, which is a disadvantage.<br/><br/>I'm... thinking they're not equal. I'd let you have the half-fiend, but at +2LA, instead of +4, effectively 'shaving off' two of them.. and only losing the Smite Good and spell-likes.
