## About The Pull Request GODMODE has a lot of sources that toggle it. From admin-stuff to status effects, components, actions and mobs which are supposed to be invincible. It's better off as a trait than a flag, so we can manage these sources. ## Why It's Good For The Game See above. ## Changelog 🆑 admin: godmode is now a datum trait instead of a bitflag. This means the process for toggling it is a little different now. /🆑
