Code Vein - Ephemeral Wanderer - Queen's Throat/Lady in Red - 40 second kill - 20 Star NG+
As this is the exact same build as the previous video, Eva is used for Ephemeral Refrain. The difference in the two scenarios is either gift speed for Mia or gift damage for Eva. Either method of engaging this rocket-powered robot-knight is sufficient for a speed kill.
Eva's communal gift is cheaper on the ichor stack but requires more ichor (~40-50% more) to use the active gifts. However, it grants the same or more amount of drain ability on the equipped weapon as bloodsucking blades from Mia. Also, it grants an increase in gift damage for flame barrage by 50%. Whereas, in the fight with Mia, the flame barrage does about 7500 damage, with Eva, the barrage does ~10K or so.
So the choice is up to you: damage or speed or both?! But you must choose wisely! Just remember to not get hit like I did!
