About "linked fate"

[Molly]

maybe I was always wrong to use it: for example, when the voodoo doll gets a condition with a value of +2, the enemy model with upgrade gets the same condition but with a value of +1. Can't stack a condition multiple times? Today someone told me that it is possible. Could anyone clarify please?

The model gains the condition ( at +1 if applicable). So if it already has the condition it will add to the existing condition.

So if the doll gains poison+5, the linked model only gains poison+1, but if the doll then gains another poison+1 then the linked model also gains poison+1, which will add to its existing poison +1 and become poison+2 on the doll.
