Hammer Dancer

You can invoke a secret dwarven lore called the Hammer Dance (or the Axe Dance). It graces you with unnatural speed, ferocity, and focus.

You can use a bonus action to start the Hammer Dance, which lasts for 1 minute. It ends early if you are incapacitated, if you use a weapon other than a battleaxe, greataxe, handaxe, light hammer, maul or warhammer. You can also dismiss the Hammer Dance at any time you choose (no action required).

While your Hammer Dance is active, you gain the following benefits:

• You gain a bonus to your AC equal to your Strength, Constitution or Intelligence modifier (minimum of +1).
• Your walking speed increases by 10 feet.
• You have advantage on Strength (Athletics) checks.
• You gain a bonus to any Constitution saving throw you make to maintain your concentration on a spell. The bonus equals your Strength, Constitution or Intelligence modifier (minimum of +1).

You can use this feature twice. You regain all expended uses of it when you finish a short or long rest.
