She can't heal instantaneously, but she can heal varying levels of injury at the same speed. Broken leg would heal as quickly as a cut.

But the luck charm can't prevent the impossible. If Raven figures out/senses the source of magic and formulates a plan to acquire it, she still has a chance.

I believe that was from the episode with the Puppet King, when the Titans souls got stolen from their bodies and put into puppets. Raven was able to partially reverse it and take her and Starfire's souls back. Well, a cut doesn't heal that fast, so a broken leg would definitely cripple her chances.

Luck charm in itself; no. Luck charm with the keystone; maybe. Even if it cannot prevent the impossible, taking the charms seems unlikely.
