As Hamadraith says, saving constantly and reloading anytime things go sour. In its most extreme form saving after literally every move and action.
Save scumming in my opinion should be the way games are tested in that even assuming someone save scummed their brains out and faced in the end the strongest possible enemy force it should still be beatable with the right team build and tactics. If it’s not then the design needs tweaking.
As to “resetting it” presuming you mean the DDA, just take your lumps as they come for a while, limit reloading to things like you already are, mistakes and surprise impossible situations. If you limp away from a few battles it should tone down.
