Most Holy Freeze Paladins use a good amound of CB, to kill with (Holy Freeze dont do as much dmg as Shock).. .. But i would go with The Shocker (just what i like most), and then use Zeal.. It attacks faster, and then you could go use The runeword Dream for the Holy Shock aura, and then use Conviction as you own aura.. This kill the Problem with imune monsters. But if you dont have Dream, i would go with a Shocker using Zeal... (For Weapon runeword "Cresent moon" in a Phase Blade is good... Its Cheap, good speed, and -35 enemy Light res..
Hope i could help with anything..
