Whakawairua Tuahu (War for the Atlas)

The boss of this card should either be reworked or the card should be excluded from the completion bonus.
I don't have forever to chase the disabled boss through the crappy boss room.
Should I re-skill my crappy build now so I can even apply damage to this boss?

Put a high level decoy totem where you want the boss to go.

You can manipulate the boss in many ways. Some times it's enough to just stand still and attack and the boss will keep teleporting onto you and take damage when he does. Or you can use the boss's frost wall's to block where he can go, make him stuck in a corner etc. It's really not that bad if you know some of these tricks.

The boss is not dangerous or anything. She's maybe mildly annoying, but that's about it.

Manipulate her as much as you can as others have said. And maybe also swap in Dash, Frostblink, or Flame Dash somewhere in your build to make it easier to get back inside the proximity shield quickly if she teleports away. Blink skills work well there...Whirling Blades not so much. She's also easy to cheese with a Balefire if you happen to have one around.

Having to make very minor adjustments to deal with certain bosses is really not a big deal.
