Za Hando Zombie??

I was watching my friend play Dregora hardcore and he started doing BTs and had a very nice lifesteal 2 rapier that was basically 1 tapping everything.

he got up like 4 floors and this zombie rounded the corner and made a crazy sound effect (literally sounded like za hando from jjba p4)

the zombie insta killed him through prot4 gold armor whereas every other zombie was doing like half a heart of damage.

it wasn’t blighted and no modifiers.

literally just insta kill.

he had spent a lot of time on that hardcore run and we have probably played like 400 hours put together of rlcraft and never seen anything like this.

has anybody else experienced this or know what happened?
