Description:

Her base equipment is enough to generate high damage values, critical hits and brutality when activating secondary effects. So pay special attention to defence.

*The vulnerability bonus in slot 5 is activated by Arachne . If you're going to use another TU, only consider those that can apply vulnerability.

Her survival is the most complicated point, in fact she is a glass cannon, which is why the legendary item  (grade 80), runeword  and artifact  are focused on compensating for this defensive precariousness. 
The legendary item, Perseus Shield, is essential to guarantee her survival, as well as providing an excellent damage bonus.

Alternatives:

If you don't have the grade 80 version, the grade 60 alternatives are excalibur or the perseu shield .
are also useful options.
