Ambu's Charge "nearby party members max End Charges is equal to yours" has recursion/snapshots?

#2,924,572,888

Simulation with two party members with Ambu's Charge.
Player A has 1 maximum endurance charge.
Player B has 6 maximum endurance charges.

Initially, both players un-equipping and re-equipping Ambu's Charge would cause the other player to gain the party member's maximum charges.

However, after a certain point, Player B's maximum charges became stuck at 1 after re-equipping Ambus. Equipping Fragility (-1) had no effect, as it was substituted by the other player's charges.

After some fiddling, Player B's maximum charges displayed 6 (correctly), and Player A's maximum charges became 6. However, when Player B equipped Fragility, their maximum charges did not reduce (likely sharing Player A's maximum charges, which are dependent on Player B's maximum charges).

Similarly, by entering the nearby range with Fragility already equipped, it set both player's charges to 5, and removing Fragility did not increase the charges to 6 on either player.

Applications:

In version 3.25.0, it is likely that Ambu's will be able to overwrite Eternal Damnation's "You have 0 maximum charges" modifier, or be able to spread that downside to other players. Therefore, if Player A had ED + Ambu's, and Player B had Ambu's, it may be possible to exploit by having player A invest into maximum endurance charges and additional bonuses from Juggernaut, share it to Player B without equipping ED, who can then share it back to Player A with Eternal Damnation equipped and override the downside through the snapshotted maximum charges.

Request:

Please fix inconsistencies with Ambu's stat priority when multiple copies are present, and clarify how it interacts with Eternal Damnation.
