Instakill on Wallmonger - Enter The Gungeon
I genuinely don’t know how this even happened. I was so confused when the Wallmonger got 1 shot. I think the little Phoenix birds projectile insta killed him. I later instakilled the Dragun as well but the clip for that is a bit lackluster and only shows his health bar reappearing at the start of phase 2.
I think the bird caused it but idk.
