Slayer ( BtVS feat, template, and class - LA+0 but at a price)

[Westhart]

I think I detect a copy-paste error.

Ha, I missed that when I read it ><

EDIT:
Thoughts on everything:
+30 on the checks from the template seem... absurd? I would cut it down to +10, +20 tops... or make it scale maybe...

In the spoiler you should say that stakes are an exotic weapon, while that is the intention (I think) the stat block does not actually say so.

Slayer Lore: Maybe give them something similar to the archivist's ability?

DR: Nobody's writing home about (just as barbarian)

Stake Mastery: uhm... Ouch? You should add whether or not the threat range stacks with keen/improved critical. Just because of this I would make the stake do 1d6, or reduce this to d4's but that's a personal opinion... and doesn't make much sense now that I think about it
