Im looking to play a Warforged Fighter in an upcoming campaign but my DM isnt permitting UA. I found a homebrewed version of thr race and they said it would be fine but it says they fully treated as constructs and no healing spell would work on them. Mending is out too since it repairs an object but doesnt restore magic. I would only have access to the Second Wind ability, the Samurai Fighter temp hp, and my hit die.

Any advice?
