Any tips for Scepter/WH
Dagger/Warhorn is a lot easier, no question. Unless you really want the range or that 2k DPS against a large hitbox (and can hit the rotation to get it), Dagger/Warhorn is probably the better choice.
Wildfire always goes first, then DT, then Phoenix. If any of those are on CD then skip them absolutely do not wait for them to go off CD. Reason being is that when you swap to Air attunement you get permanent precision bonus but more importantly a temporary gain in Ferocity from FA.
I enjoy Sc/W much more because of the range which makes it a lot faster to breeze through mobs since you don’t have to time your attacks as much. Plus Phoenix has incredible cleave especially if you place it well. Another tip, you CAN cast Phoenix while swapping to Air, but you probably need to hit the key really quickly like 2-3 times just to make sure Phoenix goes off.
