you cant, he has to get torn off every limb but the head has to get killed manually

well uh I guess you can just set him on fire and then shoot him or let him burn
after being set on fire hes no longer invulnerable

cut his head with chainsaw or light saber

Use fire. he will be dead for a little bit and slowly regenerate

Use another vecna to kill vecna. Simple.

Or use the demogorgons head removing function.

Use Mastered Ultra Instinct Goku / Ultra Ego Vegeta / LSSJ Broly.

alt f4 him

alright time to settle this, use Florida mans shotgun or hook him up to the bud-lite generator and he will spaghettify and possibly even deatomize, this is from my experience with the generator,hell you cant even hold the florida man shotgun per fire
it has so much recoil that it flies out of your hold, dont even get started on Florida mans minigun,god himself fears that thing

set him on fire then stab head

title explains what im wondering.

use another vecna?

i know how to kill him, use fire

that will kill him

just use that one mod where you can press kill then boom he ded

you can use a demogorgon to eat his head
