Because it's a mobility restricted map, that means teleportation is disabled. I don't mind teleport being disabled, but jesus christ stop crippling my character when it's not necessary!
I also decided to expand my research since it has been a few days and create a thread for reference.
It's possible I can kill Kairyu if I use every single buff at my disposal. But if I die and lose echo, I'm going to flip out. Sirens one hit kill because their attacks stack before you reach invincibility frames, fuck them.
