So, I've been playing around with the idea of making a Light Based nuker for a long while now, but I ran into a conundrum. Since I'll be using an off-hand item, there's only one main-hand item in the game that gives Superior Radiance Lore, and that's an Alchemical Crafted Weapon.

With the new content, there's the Forgotten Light mace, which gives a hefty +141 Spell Power total to Radiance, where a Superior Radiance Lore Alchemical Item only gives 108. This forced me to ask myself an important question:

Is 33 Spell Power worth 3% Crit Chance?

I assumed the answer was no, but it intrigued me enough to work the numbers out, just to be sure. What I found surprised me.

Whether at a very high (and very unreasonably high) Spell Power of 556 or at a much more meager 321, 33 Spell Power beat out 3% crit at every turn.

Is my math correct? Is the 3% crit difference between Major and Superior Lore worth less than 30 Spell Power?

Is it even worth it to make build sacrifices to fit crit into a build?



Gear Setup 1:
21 Implement, 120 Spell Power, 160 Destiny, 80 Enhancements, 175 Metamagic = 556 Spellpower
9% Crit Enhancements, +.75 Crit Enhancements, 9% Crit Item, +.50 Crit Item = 18% Crit with 2.75x Multiplier

vs

Gear Setup 2:
18 Implement, 90 Spell Power, 160 Destiny, 80 Enhancements, 175 Metamagic = 523 Spellpower
9% Crit Enhancements, +.75 Crit Enhancements, 12% Crit Item, +.50 Crit Item = 21% Crit with 2.75x Multiplier
