Pack Curse doesn't make sense. Lycanthropy is a supernatural disease. The save should be a Fortitude save.

Additionally, Pack Curse and Alternate Form are both supernatural, not extraordinary. This also raises an awkward question. How does an alphawolf transform if he's immune to supernatural abilities? You can't just designate an ability to be extraordinary, the actual lycanthrope template has already said that Alternate Form is supernatural.

Howl- Little typo here, that should read "Intimidate check". Also, you don't make a "save" against an Intimidate check, it's a modified level check to resist.

I don't really like the idea of damage reduction based on holy water. You removed the alignment restriction, so there is nothing inherently evil about an Alphawolf. Why should he be weak to holy water? That's a vampire's thing. It seems like you're trying to make some kind of vampire/werewolf hybrid, which is...weird to say the least.

Anyway, the rest of the template looks really good. A perfect Tier Cipher lycanthrope. I like it.
