Destructo Disk

Using energy built up in your body, you can manifest a razor-sharp disk made of energy to launch at foes.  Every day, you can manifest a number of destructo disks equal to 3 + your constitution stat.  These disks do slashing damage that scales with your level(1-3, 2d8. 4-6, 4d8. 7-10, 5d8 11-20, 6d8).  Launching one of these costs an action.  However, when you hit level 5, you may fire 2 destructo disks.  At level 10, 3. Level 15, 4.  And at level 20, 5.  However, launching any more than two will cost you an exhaustion point(2 if you fire 4 and 3 if you fire 5).
