Crown Of The Tyrant (AG) + Hunter Helmet (Merce) Works???

Hello, good day.

My AG have Crown Of The Tyrant (-10% all resist) and my Merce have a Hunter Helmet (-9% chaos resist).

The question is simple: both items emit the same "purple aura." Does this work (-19% to Chaos Resist)?

Thanks.

I would also like to know. Been trying to find out but so far all I have read is that it will not stack with other crowns because it is the same aura. Possibly this is different, because they are not the same item, and/or all res is a different to specified res.

This seems to be different than the leer cast aura, which can stack, according to the wiki. So I'm wondering if it not stacking relates to aura rules, or something to do with these resistance modifiers, or most likely just independent rules for the unique items themselves.

I'm also assuming that this does stack with other sources of lowering resistances, unlike exposure which uses the largest. For example, nodes on the tree like Snowforged.

If anyone knows and is able to pass it on the knowledge that would be most appreciated. If anyone knows a good method of testing, in game or using POB that would also be very helpful.
