I paly on hardcore and have mods like thirst to make it more challeging to survive, but I want more. I'm thinking towards mods that might give me frostbite and stuff like that. If you have any mods ike that please respond, Thanks.
Added (1). Oh and mods that make bad mobs smarter and more challenging to deal with.
Play Hexxit - that's hard.
Infernal Mobs… Especially those that have extra abilities that basically make them regen health faster then you can damage them…
They can spawn anywhere where it's dark enough - I came across a Spider with the ability to blind me on the first night…
Then there towers, strongholds, castles and other places to storm - filled with a variety of different creatures. I've come across pirate ships with Endermen on them… (and these Endermen aren't harmed by water).
