If this is for the main game i strongly advise against doing that. It overcomplicates the mechanics for nothing and nullify the possibility of upgrading units when already fighting.
1. Find gitea repo site and clone
2. Create your new branch off main
3. Do changes on your branch locally
4. Commit and push changes to remote version of your branch
5. Raise PR from remote version of your branch to main
who should I ask for to make pull requests for these stuffs? (only the stuff that is "uncontroversial" like the hero speed bonus applying to hero itself if applicable, or ele garrison inside forts etc so that the gitea isnt clogged with balance stuff) ANYONE UP FOR THE TASK? XD
