Who should I use for 6.4.3 Dark Hawk?

I think that's the quest with the annihilus on it. He was worse than the Dark Hawk for me, you should definitely check around for good counters for him.

Check the advice section / youtube videos.

If you don’t want to rank intone up for this one fight, Doom or ramped up Aegon might be your best bets. With 5/65s and maybe watching a YouTube video on him to get familiar, he shouldn’t take you more than a couple revives, and definitely should be solo-able.

Quake was one of the top options, try to learn her for future usage tho...

Best I feel for your initial completion is
Boosted Corvus
+ Proxima(synergy)
+ 200% cosmic power boost
+ 2-3 revives.

Also I feel like you seriously need some mastery improvements too.

Thanks for the advice y’all! I decided on the annihlous path, and probably bring Corvus and Hype to counter DH
