Last Chance was created by Dason Concordia to rival his often stronger opponent's strength, but this power often results in death after extended use, that is why it's your "last chance". This is a booster power that takes extreme levels of concentration. It makes you invulnerable (or pretty close to) while also boosting your strength and speed by how much power you are willing to give with either death or KO as a side effect from prolonged use. If you cut it off before your amount of posts you will still be conscious and you will be drained realistically. Only Dason or a fellow master can teach it, but as of yet only Dason know the power.
