POE2 The Prisoner Immediately full health off Minion Master builds

Yes I'm aware of "direct minions". I've used it. Cannot progress past this fight due to his healing mechanism's interaction with minions even when using Acrimony support. Blood daggers also can travel to the edge of the arena from the middle without any visible projectile.

Hotfix/free respec/refund?

Same issue here, wasn't even close to dying in the fight but just watched the boss heal to fill health over and over again before i had to quit.
Moved onto a different character.

Can confirm, any minion in the area when he does the Blood Explosion ability will heal.
