Summon 3 Zombie Dogs from the depths to fight by your side. Each dog deals 30% of your weapon damage as Physical per hit.
I don't know, I can't seem to make my Arcane Orb deal as much damage as my Zombie Dog:
Anyway, many people I play with are rather confused about the buffs to Magic Missile and Hydra. They already were viable in the live game. Like Bagstone pointed out, it's the spenders that need help and channeling spenders actually got a massive nerf with the 30 AP initial cost requirement on top of the channeling costs. It's insane.
That's not a fair comparison tho, since that dog is as strong as more than 6 dogs if you have the 3 passives and TMF, you also need Mask of Jeram.
Not really fair to compare an ability with 2 legendaries and 3 passives to make it stronger.
edit:
Looked at your video, you even had another legendary just to boost the dog damage further, so that makes it 3 legendaries and 3 passives to boost the dog. If you want to compare the abilities do it under the same circumstances.
There are no legendaries that specifically boosts Arcane Orb and that's not a problem with the spell, that's a problem with legendary diversity.
