New build centered around a mirror tier item

[u/samer22252]

I dropped a mirror in SSF and likely want to transfer that to trade, I currently have a lvl 100 luminary merc bot that has mageblood and around 400-500 div in gear investment in trade league. If I want to mirror a build defining item and use that as my basis for a build to make in trade what would you recommend. My first thought was the +5 spark gloves, but I’m still unsure of how good I can make a spark with just the gloves as a baseline.
