Hello, my DM gave me an item that would give me a +1 bonus to both attack rolls and damage. I have managed to imbue the item with the attack roll bonus, but I can't seem to find a way to give it the damage roll bonus. Is this possible?

Unfortunately there is no mechanical way to automatically add +1 to all of your damage rolls.

Well, that's an unfortunate shortcoming that you'd think would have been implemented from the start...

 you will find a lot of those unfortunately.

so you actually can, but I had to look this up on YouTube. You need to go down into into Modifiers, hit bonus, for the type of bonus you hit magic, and then you put in your average +1 in the fixed value portion.

That’s on a per-weapon basis. There’s no way to make 1 item that gives that benefit to all your attacks.
