She's not that hard to solo and has little HP, but you can't snare or root her, she hits for 23-95 (no flurries or enrage, or stuff like that), dispells, and if she's weilding the sword, procs for 83dmg.
I wouldn't suggest doing her without a healer (if you're melee) or without C3 and sow/RS3 (if you're a caster)
