Prominence II The bosses kill in one hit

[sharp wharf]

We made our own server that- to play, explored the world, made a netherite armor and went to the bosses, and Nether Gauntlet just kills with one hit, after 2-3 deaths netherite armor just broke. And so it is with every boss.
Decided to check in singleplayer, created a world, summon a boss, and to my surprise he had very little damage.
Apparently, damage and health of mobs increases with world exploration. How can this be disabled or fixed, what mod does this?

didnt an update happen for mob scaling

[fringe yew]

had the exact same thing happening on my server. myself and others have essentially perfect armor, but get 1 tapped by the nether gauntlet. our server is still on 3.0.1 so im not sure if this has been fixed on the newest version or not.

you need to update the modpack

and you need to progress through the skill tree and armor to survive bosses
