After clearing Gladiator with a single-mastery Occultist I decided to try with Shaman as well. It actually did impressively well. I wasn’t paying attention when I spec’d into this build so I ran the first 3 waves without Celestial Powers bound to anything. It went much better after I bound them. Because of a lack of pet and support skills on Shaman, I burned some skill points on maxing Wind Devil, Storm Totem, and Grasping Vines, so I guess you could call this my first hybrid build.
Seriously sigatrev, you will make the devs think that pet archetype doesn’t need any buff …
On a side note, it is interesting that using single mastery give you so much points to Max all the pet in shaman. Also, I was surprised that the your gear set can still give an acceptable %damage multiplier for lightning.
