User blog comment:OmniTrio3/Paris Trial/@comment-27957957-20160317184032

Things you want to use is BB on Spark (Chrome, Rhoa), A UBB that restores BB to full like Haile, and Charla because after you knock out Rahgan and Charla, Paris will prevent all BC drops so you need something to restores your BB to full if the sparks are not enough. High Damage buff because you have to push certain tresholds to proceed and burst down the units that Paris summons. Triton's Shield Buff and elemental mitigation to back up your main mitigation skills (Drevas, Riehard or ideally Allanon for all elements). Lastly leaders skills that provide damage reduction from thunder types like Eldora can help too. It's a trickry trial, I hope this helps to some extent.
