This modpack adds tons of content while still trying to provide a decent vanilla-hard like challange. Overpowered enchantments or spells are disabled or nerfed.

Challenges/Settings

Villagers

Villagers cannot bread nor can they switch profession once they have one. This makes villagers very valuable and gives players incentive to find more villagers in the world. Some villages are overrun and will only have enemy mobs. Sometimes villagers can be found outside of villages like on boats.

Healing from food

Start off with more hp than usual. However regeneration by food is very slow. Healing can be done through sleeping, spells and potions.

Reviving

If you die, you will enter a dying state from which you can be revived or, if you have enough xp, can try to self revive at the cost of some levels. The revival of another player will reward the savior some xp.

Dying

When you do die a totem of holding will retain your items. If you die again before retrieving your last totem, the previous totem will be destroyed, dropping the items on the floor.

Day cycle

A day will take 16 minutes. The night takes 9 minutes. Sleep to speed up the time.

Bed Comfort

Sleep to recover hp at the cost of food saturation. Sleeping in a familiar area will allow for better sleeping quality just as sleeping in a better bed does.

Waystones

Waystones can be found or crafted. Traveling cost are fixed regardless of distance. However traveling to another dimension will cost more xp. For shorter distances it might be better to use a good old horse to get around.

How to enable shaders

to Enable/disable:

Go to Options > Video settings > Shader packs
Select shader and make sure shaders are enabled or disabled
press Apply or Done

Content

Hourglass
Change day and night cycle timings in config. This modpack's default is set to 15 minute day and 9 minute night. Night skipping happens when all players sleep for 30 seconds. This makes it not too easy to always skip the night so that it would never be dark. But still possible to skip the night.
Farming and cooking
Croptopia and farmers delight add lots of extra ways to make highly saturated food. More effect means better food. Also there are some addons for farmers delight like for example ends delight which adds some interesting food.
