Does anyone know what type of dmg is done with portal barb?

Is it magic, physical, or some new typeless/pure/true dmg?

I want to know which renewed will help improve the build.

Damage isn't being done at all. The portals are taking up space that the monsters need to exist in, and they can't, so they instantly die. If anything you could name it something like 'void space' damage, but someone who is more versed in the technical side of bportal can confirm. or can confirm.

Emiliaaa is right but to expand a little essentially the portals create deadspace that expands and when that intersects with a mobs position the mob is forced to poof due to a check on whether or not a monster can exist in a certain coordinate or not (the same thing that stops mobs from spawning out of bounds or inversely what allows flying mobs to cross certain kinds of terrain).

Normally this check would just stop the monster from spawning in, since it’s already there though, as a failsafe it gets the same “you do not belong here anymore” instant kill that warlock demons and other summons get when their player leaves the game. The only difference is that since it was an actual mob and not a summoned creature, it has a drop table and since it’s not out of map bounds, it still drops its items.

I’m pretty sure is the expert on this subject.

getting pretty close to forbidden knowledge
never do portal spam inside those voids in the tomb walls
collapse the universe

This, the town portal essentially acts as a black hole, absorbing everything in its path

brain damage. it's brain damage dealt.

so it does dmg to the code of the game
got it

Yes thank you. As the #1 portal barb rotw east I can shed some light on the details of setting up a reliable bportal. The first thing you need to understand is
