About Nightmare Mode

From Modrinth

A datapack that expands on Minecraft's hard difficulty to make the game exponentially more difficult!

Nightmare Mode Header

Nightmare Mode is a relatively simple datapack that aims to expand the difficulty of the game past Minecraft's currently hardest difficulty. The datapack does a variety of things to achieve this, most of their mobs have had their HP, attack damage, knockback resistance, and movement speed increased. Lots of different mobs can also spawn with a myriad of different armor and weapons, all with random enchantments. If you die early on in your first play-through, don't worry, this datapack is immensely difficult!

A creeper|The creeper, while its always been a dangerous mob, is now far more dangerous than before. Alongside its aforementioned increased stats, its explosion size is larger and it explodes almost instantly! You certainly want to keep your distance from creepers! ---|--- Zombies have also become much stronger! They all have a chance to spawn with a variety of different weapons and armors, enchanted too!|A zombie A skeleton|The skeleton, much like the zombie, can spawn with a variety of different armor and weapons. The skeleton can also spawn with melee weapons occasionally, so watch out! The spider also boasts its own new changes. It can spawn with a variety of positive effects, in addition to its increased base stats! Such effects include regeneration, speed, jump boost, strength, and even invisibility!|A spider
