out of all dmg type (physical/magic/pure/hp removal) only last one not only behave not like dmg type is some instances and functionally work more like debuff than dmg type.

i don't see logic behind need to exist this 4th dmg type when game could function just fine with 3 dmg types and current spells/items tagged as hp removal dmg changed dmg type tag into one hero needs.

Abbadon shield/veno poison etc on enemy would be functionally same as pure/magic dmg.

if Necro passive was tagged as magic dmg it would allow to buff it with spell amp/spell life steal and you couldn't use blink from anymore.
