Code Vein - Ephemeral Wanderer - Queen's Throat/Mia - 44 second kill - 20 Star NG+
The Ephemeral Wanderer is akin to the Successor of the Breath boss battle. For this battle, the extreme weaknesses of pierce and fire come to play.
For this kill, regular Mia is utilized as she grants an additional stack of bloodsucking blades for massive ichor recovery on strike. This is crucial to staying "in the fray" casting each of the active gifts. Mia's communal gift is used as well in order to drastically reduce the cooldown of the active gifts. This allows for almost continuous casting. Every now and again, a sword strike must land to regain ichor. As this fight is mainly focused on flame barrage as a light gift (paired with intensified noble silver for maximum scaling), Dancing Blaze is employed simply for stagger potential. It has a raised stagger chance as compared to flame barrage. Once staggered, load up on the casts and ichor as much as possible. Once he's out of the stagger, he will transition and explode. Watching for the jet-pack boosting around the arena is the most difficult attack to avoid. The rest of the time, running in circles is very much his weakness as well!
Hopefully this shed some "light" on this fight for those struggling to make it through!
