This is a pretty basic combo I learned with help from the great people in the Wizard discord! I get a lot of mileage from it in PvP, as it provides good burst while giving you some all-around buffs thanks to the skill add-ons. For the table I put the skill name at top, base hotkey below, and is performed in order from left to right.
Flame Knot | Hellfire | Magma Bomb | Trembling Earthquake | Water Sphere | Aqua Bomb | Barrage of Water | Cataclysm |
Q | W+F | RMB | Shift+Z | Hotkey | RMB | W+RMB | Shift+F |
Give it a shot and lmk what you think, I'm not the most skilled PvPer so I'm sure it could be improved some!
