My first datapack, pretty simple but very original!

With this datapack you can turn players into berserkers
How it works:
When berserker have 10-8 hearts, nothing happens
When berserker have 7.5-5.5 hearts, he gets strength I and speed I
When berserker have 5-3 hearts, he gets strength II and speed II
When berserker have 3.5-1 hearts, he gets strength III and speed III
When berserker have half of a heart, he gets strength V and speed V

To add yourself as a berserker, type in chat /function berserker:addplayer
