Not at all possible without 0ceal0t's VFX Editor plugin! So easy, a RPR can do it!

Eventide has been altered to only emit VFX in front of you, instead of behind you, and has been altered to not follow your character around. Also included separately is a replacement for Flood of Shadow, which turns it into Shadowbringer.
FIX: Fixed projectile to ground, so it doesn't fly off into the air on larger enemies.
This is an animation/vfx replacement for Shadowbringer to become Eventide.
