Make Unity benefits toggleable

[DYVNNE]

Fairly simple request, as a more casual player and someone that also quite enjoys the lower level gameplay and story, allow Unity benefits to be toggled on/off.

 

Starting the game off with like 40k HP when you are supposed to start with ~300 HP feels wrong and kills any challenge the early game could pose, on top of one shotting any early game monster. I feel like this would be a pretty harmless feature to the game as any players that do want to rush can keep the Unity benefits enabled.
