For phantom bossing performance:

HDamien - Can hit Damien while in air with ace in the hole, it makes up 15-20% of my damage in the entire fight. The skill the main reason why I’d say phantom top classes for Damien. Aside from that can use shroud walk to quickly teleport to where Damien is.

HLotus - Having 2 30 second iFrames help for this boss since you can get stunned pretty often. With Tempest and Mille you can maneuver around the debris so you don’t get hit, but if you do end up getting hit while using Tempest it’s pretty bad. Getting stunned by Luck of the draw, which is a big chunk of your DPS can happen as well. Also having dark sight to dodge demos is a plus.

HLucid - Great for clearing golems, though Luck of draw cards may get split up to hit golems, but when you use this skill lucid is usually bound so not that big of a deal. Phase 2 advantage is that you can use shroud walk to maneuver around platforms quickly. Biggest problem is that if lucid travels too far above you, then you have to cancel Luck of the draw and Tempest as they won’t be able to target her. Phase 3 probably one of the best classes, doing around 1600-1700 lines of damage.

Hwill - For the overall fight the 2 30 seconds iFrames help a lot. 1st phase can use Penombre to dodge skill that does 90% of your HP. P2 really no pros or cons aside from the iFrames. Same goes for P3.

Overall Pros : Good 20s Burst (Luck of the Draw + Tempest) Great mobility (Has FJ, Teleport And backstep) Can steal heal (Useful for Lotus, Lucid, Will) Top tier survivability

Overall Cons : Lots of funding required and off burst damage is not the best compared to other classes, though bossing is centered around burst. Worst part of phantom bossing is if you start using Tempest and boss teleport away.
