Corpse Crafter feat chain, Desecrate Spell, Awaken Undead spell

[Nezkrul]

If a necromancer creates an undead creature using the whole feat chain for corpse crafter, in a desecrate spell, and then casts Awaken Undead on the normally mindless creation; what would all that buffing do to the creature's CR?

By RAW, nothing. I'd probably rate it as +2 to +3 CR. Some creatures (the big bruisers) get a lot more out of those buffs than others (casters).

Well depends what you turn it into. Zombies, Skeletons, and Wights will likely reduce on creatures with a CR 10+. However, the Create Undead spells plus the use of Libris Mortis templates will likely give options that increase it which could be better than what they originally have. However, it depends what no amount of corpsecrafter, desecrate..etc will make up for high constitutions or great special abilities.
