Kill her like a Tarantula, but be aware that she is quite a bit stronger.
Sorcerers: This is a VERY easy boss for a sorcerer lvl 33 or higher, wand of inferno and exori flam will be all you need aside from a few exuras to restore your hp from time to time, it's hard to outrun this boss but blocking it won't harm you THAT much, lower levels might consider using a wand of draconia or dragonbreath with Flame Strike while healing with Exura or Exura Gran when your Hit Points get below 150. You might need some Mana Potions on lower level, but from lvl 33+ around 300 will be more than enough to bring it down.
Knights: Stand still and kill it with Melee. It is strong to Physical Damage, so you might consider using a fire-enchanted weapon on lower levels. Knights with skills 60/60 or more shouldn't have a problem killing Hide.
