MagDK PvP Top Metah: Rallying Cry - Chevalier-dragon Construire - ESO

Magicka Dragonknight is an extremely potent playstyle in pvp and can provide massive burst damage, annoying CC, great sustain, and jaw-dropping survivability at the same time. Like any build, the person using it matters greatly but if you take the time to learn the way of the DK, you'll be pulling 1.5m damage every battleground.
For solo play, Burning Spellweave and Ironblood is unmatched in tankiness and lets you 1vX nicely.
For group play (2 - 4 people) 1 person running Rallying Cry is a great idea as the crit resistance it provides is VERY nice, and 1 person should be running molten armaments on their bar.

Vampirism is optional, and not recommended if you use a sword and board. 
Cinder Storm is a free heal because the reduce cost glyphs with infused bring the cost down to 0. Casting it will also grant you 990 stamina every time thanks to the Helping Hands passive.
Armor Potions are one of the cornerstones of the builds, as it provides a stacking 5280 armor buff and is what can push you to 35k+ resistances while maintaining huge burst.
