Gaining XP as a wizard

[Raavak]

You can maybe melee and nuke until your low teens, then root/nuke until you get Pillar of Fire at 16 along with some SoW potions and can quad kite (without snare).

Try to form AE groups with other wizards and enchanters as soon as you can. I don't know what level that becomes viable, but I remember doing some Mistmoore Castle years ago, with a fleet footed bard to pull.

One warning, once you taste PBAE exp you won't ever want to go grind solo ever again.
