healing/regeneration and non-surgical bullet/arrow expulsion

[Rupert]

The way I see it, Regrowth is a very expensive advantage, so much so that most people consider it considerably over-priced, and so it's ability should be interpreted generously. The advantage says 'limbs and organs', so I see no reason it shouldn't allow regrowth of damaged or destroyed skeletal muscles, bones, tendons, etc. as well even when a limb isn't completely gone.

At its core it's the ability to recover from permanently crippling injuries, so whether or not the crippled limb is gone or not shouldn't matter.

Whether regrowth includes expelling foreign matter, resetting cosmetic surgery, not scarring vs. scarring and so on is, I think, a matter for each instance of the power.
