the video was supposed to be linked as a playlist but i guess that does not work, so here is the link for anyone wondering where the rest of the video went: www.youtube.com/playlist?list=PLy6RYsckhq5ZZQEfpKhPIv8sCEXsfLeQT

Leveling is a very configurable, vanilla style datapack that focuses on leveling up the player trough kills, so that the player gets stronger the more they play the world.

currently version 2.0:
Max Level is 20

Every Level gives you 1 heart and 1 point of luck, by default

Kills to reach certain levels:
0 = 0
10 = 1
30 = 2
70 = 3
150 = 4
310 = 5 (at this point you have the vanilla health)
630 = 6
1270 = 7
2550 = 8
5110 = 9
10230 = 10
20470 = 11
40950 = 12
81910 = 13
163830 = 14
327670 = 15
655350 = 16
1310710 = 17
2621430 = 18
5242870 = 19
10485750 = 20
(i am aware that its unreasonable to get 10 million kills, which is why i'll include a way for you to change it in the youtube video above, the reason i made it this hard is because i want it to be harder the further in the game you are to get stronger)

to see information about the commands, use /function leveling:help
