Shaitan's Black Rend is supposed to be an 'unresistable' form of damage, yet it seems that it can still be evaded as per 'spell evasion'. Given that its damage is already relatively low (to counteract it being unresistable), I think this is not intentional.

Unresistable simply means unmodified by Defence/Resistance stats. All type/general resists (Such as elemental resists, etc) apply as normal.

Example: Guns are unresistable. They still hit weaker damage against Pierce Resistance.

So is evasion considered a 'resist' then?

[Soapy]

Unresistable means it ignores these two numbers.

That's it.
