best merc for light sorc?

[AlabasterFilth]

I am making a pure light sorc (without infinity). It will be used primarily for key-running. I am wondering which merc will be better for me to use: defiance aura, or holy freeze aura merc. I've had good results with both, but am unsure which is best to use for a key/rune-runner

holy freeze is better than defiance since your defense is usually pretty low anyway

might merc is not a bad option either, since you need to be able to kill some light immunes as well

just experiment with them to see which is more useful to you

I've always preferred HF to Defiance myself.

for non cold sorc go for holy freez.. you need the chillingfactor more than the extra defence
