Boost items that have conflict

Question

I've seen a thread here where it was asked about support spells with conflict. But what about boost items like Hireling's Food, Jean Pierre's dishes, berserk/mastermind/sharpshooter potion, etc? What are the conflicts between such items? For example, if I use one of these items, what kind of item boost can cancel the other? Is there a "rule of thumb" for it?

Answer 1

They stated on the forum that Hierling's food share cooldown of 10 minutes with the Hot Cousin's dishes.

Regarding further temporary boosts, they stated that they are not stack and actually overrides each other.
