Please tone down Manassa's damage reduction when delirium is active on map

In the map confluence, spring and i think there is one more map where Manassa the serpent queen is present, if delirium is active, she gets an insane amount of damage reduction, it's ridiculous.

Don't get me wrong, I'm not complaining for the sake of complaining or skill issue gitgudnub garbage etc. She's overtuned with her defenses when delirium is present, compared to the other bosses + delirium. I can melt those in 2-3s while Manassa gets a 95% damage reduction or something, which makes the fight 4-5 times longer than needed, again, compared to most other bosses.
