Frost Auradin (Which uses Holy Frost right?) Would be kind of useless, no offence. There are way better options for you to use. + you can just get a merc with HF, which then lets you be able to use other arua like HS or convition. The way i set up my pally is I gave him dream helm/shield and maxed the Syenrgys to HS and convection. This makes you do HIGH damage while the enemys res is lowerd be a good deal. Then all you have to do is buy a HF merc and your good to go.
