Vulnerability effectiveness "Doesn't stack within single item" means?

[Striker]

Hey.

I have a simple question. After the patch a "Vulnerability effectiveness" bonus had a phrase added that it doesn't stack within a single item.

So how does it work now?
If I, for example, have a signum, weapon and armor with psalm code with this bonus does it mean that I get only the highest % of all 4 applied?
Or does it mean that I'll get bonus for 2 gear peaces+psalm code (if it's higher than armor bonus)?

I actually just ran test on it.
Enchant, psalm and shard do stack once within the same item.
You can't have 2 psalms or 2 shards in the same item.
So, on my belt item I had a 20% enchant + 12% shard and +50% psalm and all worked

I tested on the last campaign boss with fear aura + vuln on debuff signum for gutanteed 10 stacks, with one enrage token and heat aura damage ticks.
I had a total of 128% vuln efficency on other gear.
only belt enchant: 2251 damage
belt enchant + shard: 2329 damage
belt enchant + psalm: 2575 damage
belt enchant + psalm + shard: 2653 damage

Thanks.

But that's really strange, what and how doesn't it stack then.

2 shards dont stack and neither do 2 psalms within the same item.

Thx.

Though so. Seems like bad description though. More like doesn't stack from the same item type or source in one item.
