My main damage sources are Blazing Spear, Elemental Blockade, and Puncturing Sweeps while Inner Light is slotted for Prophecy. Right now my spare skill slot is Solar Barrage which gives an additional AoE DoT as well as Empower for Light Attacks.
I'm wondering if slotting Entropy in place of Solar Barrage and adding Meteor as my Ultimate will be better than Solar Barrage. 3 Mages guild skills = +6% Magicka and Entropy gives me +20% Spell Damage.
I'm leaning towards Entropy+Meteor.
