I'm rocking two Health Wards, and the rest paladin power/arcane. He's tanky enough to survive a couple rounds without a shield or heal now.
I wouldn't recommend ever upgrading a sorcery talisman to five stars. Most of the high end bad guys at end game do true damage and a sorcery talisman will be useless at this point. I'd like to swap out my health ward for health overwhelming, I know this is nerfing his magic stat even more, but it's an extra 4k in hit points. End game bad guys hit hard and a turn spent healing is a turn spent wasted.
