THIS IS A DATAPACK! You need to either add it to your world's datapack folder or use an automatic loader such as OpenLoader or Paxi.
This simple datapack rebalances the Gamer Axe when using Better Combat. It is a heavily unbalanced weapon due to its very high speed, so this adjusts the bettercombat damage calcs to deal way less damage per hit, making it still viable, but not a really broken weapon. This is best accompained with the ReBalance mod.
How to install?
Download the zip and put it in your world's datapacks folder.
Alternatively, install openloader or paxi, and put the datapack inside their data folder.
