Homebrew:Seven Leaping Dragon Stone

Wondrous item (hearthstone), very rare

• You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strike.
• You can roll a d4 in place of the normal damage of your unarmed strike. Increase this die to d6 when your highest class level is 5. Increase this die to d8 when your highest class level is 11. Increase this die to d10 when your highest class level is 17. If you are a Monk, you may instead add d4 whenever you would roll your Martial Arts die.
• When you use the Attack action with an unarmed strike on your turn, you can make one unarmed strike as a bonus action.
