So this is my Mag Nb pvp build for cwc, viable in CP and No cp.
the gear is all very easy to get. cost me under 30k to get of it crafted and bought. *not including upgrades or glyps ofc.
GEAR - 5/1/1 (light x5 for dampen)
5 shackle breaker (head,chest,legs,boots, destro and resto)
5 war maiden (arms, belt, 3x jewl)
1 domihaus on shoulder although 1x mag regen via shadow rend or 1x kena works well too
Traits/glyphs
Full impen preferably, i run 1 divines as i am yet to get an impen domihaus and don't mind a bit higher regen.
Flame Staff (front bar) NIRN - anything. I run shock but may move to reduce enemy weapon dmg or ofc you can run poisions
Resto Staff (back bar) Infused - Berserker
Jewl - 3x regen glyps. but i do swap 1 or 2 spell dmg glyps on my jewl at times. this will bring your fully buffed swallow soul up to over 12K but leave your regen at just under 2k ish.
Mundus- Atro, if you aren't dunmer i would recommend mage for high elf and breton due to regen and reduce cost coming in their passives.
Tri stat food, if you feel confident you can try witch mothers and run dmg on jewl but i like to dodge roll alot so it works.
Fully buffed tool tips of Merciless resolve, swallow soul and soul harvest.
