Trait selection for lvl 30 ele?
Well nowadays you can change traits on the fly. So choice isn’t w big deal. Try them all.
Fire: defensive dps (aka dmg enemies when focusing on defense)
Air: mobility
Earth: defense
Water: sustain
Arcane: burst
This is just for the first minor traits. Have fun and good luck.
Blasting Staff under Arcane would be your first choice if you’re using a staff to attack. It’ll take two points though.
