In extreme circumstances, such as the threat of death to one's self or one's loved ones, the body will release self-imposed restraints to accomplish extraordinary acts at the risk of permanent damage or death. You have learned how to tap into a lesser mental equivalent of this phenomenon to extend your limits at the cost of recovery time. You gain the following benefits:

• Once per long rest, whenever you would be hit or affected by a spell (after the check or save roll is made but before the effects take place), you may have the caster reroll to hit you or you may reroll ability save to resist the spell. You must take results of the second roll.
• You can use your action to restore a number of spell slots, of any level, determined by your level as described below. Any spell slots restored by this action do not get restored during the next long rest you take. In other words, you must complete two long rests before those spell slots are naturally restored. These spell slots still require two rests to be restored even if they are restored through other means after using this action and before resting twice. (NOTE: You will want to keep track of spell slots restored this way, as the ability is available once per one long rest.)
  • Level 12 : up to 3 slots
  • Level 13 - 14: up to 4 slots
  • Level 15: up to 5 slots
  • Level 16 - 17: up to 6 slots
  • Level 18-20: up to 7 slots
