After such a long life, you've learned how to use sorcery points more than the normal sorcerer though it's very demanding. You gain extra sorcery points equal to half your sorcerer level rounded down. When you choose to use one, the dm rolls a d4. if it lands on an even number, the danger point acts as a normal sorcery point. when it lands on an odd one, the DM chooses a reasonable backfire/alternative effect.
