34 Druid - Getting Ring of Great Divide Spell

[Regulus77]

Hello. I just dinged 34. But I'm having a hard time understanding how to get this spell. The wiki says this Vendor sells it:

Phillip Aghllsews
Race: Yak Man
Class: Shopkeeper
Level: 50
Spawn
Zone: The Wakening Land

I asked a senior Druid and he told me to go to Great Divide and get a tooth which I did. He said that Vendor might kill me. Not sure what the tooth does but please tell me how to get this spell.

Thanks again
