I'm Justin and have my own Nitrado server (For Minecraft)

I play with my friends with mods and have around 60-70 mods inside.

My proplem is: That some mod that makes the monsters get stronger day by day ne spider has simple effects and 50 lives… O_o

So I ask you which mod it could be?

Thanks in advance
