Spellstitched Undead are LA:-

[RoboEmperor]

Common misconception actually, the 3.5 version of spellstitched is in Complete Arcane. LM merely references it in a table, the MMII version specifically, although that's purely because CA came out a month after LM.

The sample Spellstitched in CA has a LA: -, but so does the base Ghast, so that's nothing to go by. The template itself has no LA entry, just a CR one.

Huh, it seems you're right. The update was addressing the ghast, not the template.

Since CA is the most recent printing it is the one we use, and since it doesn't have an LA entry, as Silva Stormrage and torrasque666 said it defaults to "Same as base creature".

Nevermind! Sorry for the false alarm. >.<

I thought the template gave bonuses to those skills and wasn't talking about the Ghast since it says re-apply the template.
