you only need to use ruby and xiao note you must never equip their weapons with the ice
attribute. get many auto repairs and revival powders . heres the hint just hid in behind
the posts beside or near her and keep on shooting her with xiao and when it starts to say
no effect switch back to ruby and again when it says no effect switch back to xiao keep
repeating this procces and the quin will be dead and you shall aquire the moon orb

get a whole lot of money and buy a lot of those fire bomb things for the shop run around
her and keep throwing them

use toan when she's sheilding dont use ice then ruby when she's attacking dodge though oh
and hide behind the poles

get ice gems than throw it at her
