Q486: Where is the online source that lists the variant of the half-fiend template based on a succubus? It's not http://www.wizards.com/default.asp?x=dnd/we/20060630x . If I recall correctly, it was applied to an Annis Hag.
A486: Right
here in fact, you just have to look a bit harder. It's split up over the examples in the design process and on page 3 it gives the example, applied to a Sea Hag, not an Annis. ;-)
This is a
very useful variant on the template, especially if you pick a Huge fiend for that size increase (since it carries a +1 CR, but not an LA boost).
Though the article does contain a bit of RaI info that is incorrect by RaW ("Remember that HD for determining spell resistance means racial HD, not those gained with class levels" when the text in question simply says "creature's HD.")
Suggested stat mods for the
succubus version were Str +2, Dex +2, Int +4, Cha +8, +2 NA, detect thoughts 3/day at 1-2HD, suggestion 1/day at 3-4 HD, DR/good, fly speed, and other stuff basic to the template.
