Multiplayer difficulty

[round rover]

Hey our group reached the second boss and it's really tough. On our server we set the coop correction multiplier to 0.
What we saw is, that the boss is still scaling to more player. With 1 player there are 11 health parts. With 3 player it was like ~25 didn't know the exact number. Is this intended or is something working wrong?
These are our settings:

Mobhealth:1.25
Mobdamage:1.25
Coopcorrection:0
Bossdifficulty: Normal

Thanks for your help

scaling does happen in multiplayer, if you do find it difficult try changing basic diffigulty params first instead of just multiplayr scaling - that's an additional layer

The open world is fine. Just the boss fight is on another level.
