I'm nightblade, with all but 2 points spent in magicka, I'm using Swallow Soul that heals me for 25$ of dmg done, also newly unlocked Siphoning Strikes but barely can finish off any cast to healme before she gets to me, it's all weak healing, and before I go through aplying debuffs not to mention casting any heavy or weak attack to utilize Siphoning strikes I'm already dead. Slowing doesn't help since she's caster so the hits even go through the only bit of wall I can hide behind, no matter how far I kite her, her spells always hit me.
