This data pack adds Slender Man into your Minecraft world as a hostile antagonistic force.

[ATTENTION] You need to use this resource pack, otherwise the data pack will not work.

If you do not now how to install data packs, watch my tutorial video.

Slender Man has a chance to spawn in any forest biome at night. He has 3 different phases that change his aggression and behavior. Slender Man natrually progresses through these phases along side the player when they progress in their world.

If you want to know everything there is to know about this data pack, watch my showcase video here:

[SPOILERS] Complete feature list:

In a new world all players start with slender difficulty 0:

Slender difficulty phase 0:

custom model (regular one)
custom sound
random spawn chance if player in any type of forest at night
stalks player and disappears if looked at

After obtaining iron armor achievement, difficulty phase is raised to 1

Slender difficulty phase 1:

custom model (with tentacles)
custom jumpscare sound
random spawn chance if player in any type of forest at night (a bit higher chance than phase 0 slender)
spawns way closer to player, jumpscares the player that way
blinds player and then vanishes

After obtaining diamond armor achievement, difficulty phase is raised to 2

Slender difficulty phase 2:

difficulty of the world must be easy or higher, because slender is a hostile mob
random chance that boss fight encounter starts if player is in any type of forest at night
1 out of 8 random warning messages appears in chat
creepy theme music starts and gets more intense until slender spawns
slender spawns and the fight begins:
- during the whole fight, an intense slender theme plays
- player has darkness effect applied
- black smoke envelopes the player and slender
- slender moves slowly towards the player to damage them
- slender’s attacks apply wither effect
- slender has a random chance to teleport around the player during the fight
- slender has a random chance to teleport the player around himself during the fight
- slender will teleport if the player was close enough to him for more than 3 seconds (so the fight lasts longer)
- if the player dies or runs away, slender despawns and a grace period is applied (slender cant spawn for the rest of the current night)
- if the player kills slender, he will drop 1 out of 8 random pages and the grace period is applied (slender cant spawn for the rest of the current night)

Players can throw pages into fire or lava to burn them:

a custom sound will play
the current number of pages that have been burnt is shown in chat
if 8/8 pages are burned, a creepy sound plays and slender is banished from the world
slender cannot spawn in the world anymore if he is banished

This is the “end” of the data pack and its progression
