I was looking at the most recent datamined class info so that I can pre-plan the wizard skills I want and chose the following damage increasing skills:

Frost Nova Bone Chill
Enemies take 60% more damage while frozen or chilled by Frost Nova.

Cold Blooded
All damage dealt to chilled and frozen targets is increased by 10%.

Unwavering Will
Standing still for 2 seconds increases the following attributes: Armor: 20% All Resistances: 20% Damage: 10%

Audacity
You deal 20% additional damage to enemies within 15 yards.


Taking the above 3 passives and Frost Nova into account, all damage done to frozen enemies within 15 yards while I am standing still will be increased by 100%.

To help get enemies within 15 yards of me I intend to use this:

Black Hole | Cost: 35 Arcane Power | Cooldown: 8 seconds
Supermassive: Increases the Black Hole radius to 20 yards and damage to 583% weapon damage as Lightning over 2 seconds.
