Whenever a dynamic event happens or when I’m with a group, I use a staff, but I find Dagger/Dagger to be the most fun. I like a more offensive build.
I start with D/D air, and go 3, 4, 5,2, → earth, 4, 2, →fire 3,2,4. Usually one enemy will be dead, but using this method I have some defensive skills up. This allows me to take down the other enemies.
If I know there will be a lot of enemies I do this: air, and go 3, 4, 5,2, → earth, 4, 2, 5 →fire 3,2,4, Arcane blast, water, 4, 2,3 → fire to finish them off.
Sceptre is good, but I find it a little too tedious while soloing.
