Spell: Great Divide Gate not listed on Terblyn Zelbus' items for sale

[Quest815]

what about these spells ? can anyone tell me where / when they will be available ?

Translocate: Combine
Translocate: Fay
Translocate: North
Translocate: Tox

seems classic but for some reason Terblyn Zelbus is only offering me one spell and this is "combine gate" which is obviously added later.

Earlier when i went to the same vendor, he didnt have his normal stock of gems / wares so something is up with him.


Thanks
