It seems that God mode is changed in 1.0. Some things I see with it:
- It doesn't say God mode on the side of the screen when enabled.
- It doesn't heal you or remove debuffs when enabled but will still prevent new damage and debuffs.
- It doesn't prevent stamina loss when running.
None of these are necessarily bad, but when I want to look around a generated world in God mode to make sure things are good and am flying around, I don't like that stamina is lost when running.
EDIT: After more testing, I realized that even though stamina reduces in God mode, you can still run full speed at 0 stamina as long as I have Flying enabled, so it's not so bad.
