Heretic of The Seventh Circle
I hope you would tell the player when picking their background that they might as well pick a different background feature?I would if the player became attached to them.
More likely, they would be waved good-bye to in the first session, and never seen again.
Anything "mechanical" about friends and allies is a fundamentally bad idea. They come from backgrounds and plot events, they don't materialise out of thin air when a character hits a certain level.
But if allies can come from background, why not from Background?
