Wither Skeletons Improve Over time

Wither skeletons get stronger the longer you play. difficulty is calculated for each player separately. The improvements are gradual, taking place every 20 minutes.

This datapack will only work on 1.19.4+.

There is now a datapack dedicated to all hostile mobs - https://modrinth.com/datapack/hostile-mobs-improve-over-time

Disclaimer

The picture shows wither skeleton in netherite stuff, but they wont drop it, so you dont need to worry about making netherite common.

Stat increase

Stats that change include:

Health
Movement speed
Knockback resistance
Damage
Better Armor (chainmail -> iron -> netherite)
Better Swords (until day 10 wither skeletons are without swords)
Follow range

Timers

Timer for difficulty is per player, and increases every minecraft day (20 minutes). sleeping does NOT forward this timer. Max difficulty is day 100+ and difficulty does not increase after that.

Commands

To test out how hard the wither skeletons are, use functions wiske:day25, wiske:day50, wiske:day75, wiske:day100 or use command: /scoreboard players set <player> Wiskdif <number>. To reset your score use wiske:reset, to reset all of players difficulty, use wiske:resetall.

Installing

Like your ordinary datapack, put zip file in datapacks folder of your world.

Unistalling

Run function skel:uninstall and remove the datapack from datapacks folder

Other

I am planning on making a version of this datapack for each common mob, then making a datapack consisting of all of them (This is the 11th mob improvement datapack I made).

Farms

This datapack will affect your wither skeleton farms, but not necessarily. When you kill wither skeletons by yourself, they will take more hits to kill or you might need to adjust the falling height. If you are using dogs to kill them, its important to stay 32 blocks away from the wither skeletons, because of how the datapack is made, only wither skeletons in a 32-block radius around players will get improved.
