Bit unsure about who to bring for this fight, was going to try use Dshulk but i dont think she'll won't work on a duped Lum, I got 7* warlock,sentinel, sinister etc but not sure who would work the best or any other options
Cheers for any advice

Pretty sure sentinel can easily nuke out. Luma don't have purify that affects sentinel heal block right? Warlock can work as well.
