Does the Corpse Crafter feat work on summoned undead?

Question

The corpse crafter feat from Libris Mortis p.25 reads:

Undead you raise or create are tougher than normal.

Benefit: Each undead you raise or create with any necromancy spell gains a +4 enhancement bonus to Strength and +2 hit points per Hit Die.

Summon undead reads:

This spell functions like summon monster I (PH 285), except that you summon an undead creature.

Summon undead I conjures one of the creatures from the 1st-level list in the accompanying sidebar. You choose which creature to summon, and you can change that choice each time you cast the spell. Summoned undead do not count toward the total Hit Dice of undead that you can control with animate dead or the other command undead abilities. No undead creature you summon can have more Hit Dice than your caster level +1.

Is this undead that is summoned effected by the corpsecrafter feat?

I understand that both Create Undead, and Animate dead would obviously be effected by the feat but was unsure if it effects summoned undead.

Answer 1

No, for two reasons.

First, summon undead is a conjuration (summoning) spell, and Corpse Crafter, as quoted by you, only applies to those undead created or raised via necromancy. If it's not a necromancy spell, Corpse Crafter doesn't apply.

But let's say that we misread that line and it really means that Corpse Crafter applies to either undead you raise or undead you create via necromancy. It still wouldn't apply, because except for the available creatures you can conjure, summon undead functions identically to summon monster. And how does summon monster get the creatures you call up?

This spell summons an extraplanar creature (typically an outsider, elemental, or magical beast native to another plane).

When you cast summon undead, you have no part in the creation of the undead creatures you summon. You therefore cannot use Corpse Crafter on them.
