Does Damage Vulnerability Stack?

I know damage immunity item properties of the same type don't stack so I assume the same applies to vulnerability but I wanted to be sure.

 

Would I be correct in assuming that if a character wore say 2 items with 25% damage vulnerability to negative energy they'd only take 25% more damage from a negative energy attack?

Both immunities and vulnerabilities stack additively.  Max of 100% for both.

 huh! I didn't realize that! So in my example equipping those two 25% dmg vuln items i'd have a total of 50% vuln from it then! Good to know!

Correct.  And equipping four items with 25% Fire Immunity each makes you 100% immune to Fire.
