Wear it. I’m a magicka Templar with 22k resistances running dw/resto. Dual swords give you almost 1k more spell power. Impregnable amour makes you very hard to burst on top of resto healing. Use whatever set with it and it works. Draugrkin is good.
Ditch vampire, lose the shield unless you’re gonna front bar it and heal/support. Rapid regen, ritual, eclipse, purifying light and Jabs gives you insane amount of self healing. Resto staves are OP, blocking is trash now
