If you don't have XWQL or Roy or SakuraDS, consider Bai Hu Zhu Que who's prism is in the trust shop. They were actually relevant on enhancements IF you had an external imperil. Most people can find space for one on their DV teams.

They have the benefit of SPR as Mag which means they use Phys killers and can take element. They imbue fire and thunder so they even help save space for those teams.

Their T2 ST 'burst' is 96x QC DR. They have a wiki damage build of about 50% of XWQL (not including their innate killers) with external imperil. They have the same T3.

BHZQ 96x4 = 384X

XWQL 120x6 = 720X (not including ~10% higher damage by build).

Compared to mages like Roy and SakuraDS at 160X they are not a bad budget build (especially with killer access)
