Umbilicus Immortalalis and Wine of the Prophet not working together.

While wearing the belt, I'm receiving the buffs not the minions and it's an interesting interaction because it allows me to get the divination buff but not the rarity buff from the flask, this is the first type of flask that has this interaction that it bypasses the Umbilicus Immortalis.

Doesn't seem to work with Mother Embrace either, and when used with Mother's Embrace it will consume the charges and neither you or the minion receive the Divination buff, unlike the Immortalis where you just receive the Divination buff.

I guess that's because the minions are only allow to get the flask effect, but the Divination Buffs are not flask effects, so Umbilicus Immortalis apply the rarity to your minions and keep the Divination Buffs on you. For the Mother Embrace case, it's your minions uses the flask, so you wont even get the Divination Buffs in the first place.

However, the description of both unique uses the term FLASK only, instead of FLASK EFFECT, so maybe it's a BUG, or GGG just forget to clarify it in the description.
