This server is built to be super hard and it really does not hold back. You start with 10 lives and every time you die you lose one heart. You only get hearts back if you eat an enchanted golden apple so death is expected and feels really risky.
All the hostile mobs are way stronger and they have special abilities. Zombies can leap at you. Creepers can breach your defenses. Spiders throw cobweb to trap you. Skeletons act more intelligent and phantoms can grab you. It makes every night and every cave run feel scary.
Bosses are also upgraded with more health and new attack patterns. The ender dragon is so powerful that you basically need a bunch of players working together to take it down.
The terrain and all natural structures in the world are overhauled so the world looks and plays different. The nether and end are better too with new special armor and weapons that help you fight the stronger mobs.
There are some quality of life changes to recipes and more use for different crafting stations. Everything is unmodded so you do not need any mods to join. There are a lot more changes than this and it is meant for players who want a really tough hardcore style experience.
