Martial Block

Your martial training has given you the ability to block incoming melee attacks, whether armed or unarmed.  You gain the following benefits:

• You gain 1 extra reaction which can only be used for this block.
• You can use a reaction to attempt to block an attack that has hit you.  Make either a Strength or Dexterity Save, your choice.  The DC is 10 plus the amount over your AC that was rolled.  For example, if your AC is 14 and the attack roll was 16, the DC is 12.
