Skeletons Improve Over Time
This datapack makes skeletons stronger the longer you play. difficulty is calculated for each player separately. Skeletons's health, follow range, armor, bows, etc. improves the longer you play. The improvements are gradual, increasing very slightly every 20 minutes.
NOTICE: This datapack is discontinued, instead use the Hostile Mobs Improve Over Time datapack: https://modrinth.com/datapack/hostile-mobs-improve-over-time
Stat Increase
Stats that change include:
- Health
- Follow range
- Movement speed
- Armor toughness Other changes:
- Enchanted Bows (power, punch, flame)
- Armor
- Enchanted Armor
- Shields
- Skeletons after day 20 (20*20 minutes) gain the ability to switch to an iron sword if player gets too close, and switch back to a bow if player gets farther away
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 skeletons are, use functions skel:day25, skel:day50, skel:day75, skel:day100 or use command: /scoreboard players set Skeldif . To reset your score use skel:reset, to reset all of players difficulty, use skel: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
