Athene's Unholy Grail and Jungle items.

Okay. Athene's new mechanic states it gains 5 AP per 25% mana regen. Shouldn't that be affected by Jungle items while in jungle, which have 225% Mana Regen boost?

There's a real tradeoff for using a support item on a jungler or a jungle item on a support, but it's an important observation to note.

Currently, Athene's does NOT take into account Jungle Base Mana Regen.

Only items that currently affect Athene's : Athene, Mikhail's, Frostqueen tiers, Ardent Censer, Redemption, and their components (but stacking all of them severely limits overall versatility, contradict each other's passives)
