I'm okay with losing SLA, Smite, SR, and hell, the wings too.  (The BoED seemed to be predicated on the notion that the SLAs are only based on racial HD, which is certainly not how most people interpret the template, but whatever.)  Mostly I figured that paring the half-fiend down to its core essentials would be easier than trying to make a case for Lolth-Touched.<br/><br/>(On a totally pointless note, KM, half-elementals are only +3.)
