- When you take the Attack action, you may use a bonus action in one of two ways. You can either make an additional attack by pulling back on the chain and hitting the target a second time. The range of this attack is 10 feet and you don’t add your ability modifier to the damage. Or, provided there is no hostile creature within 5 feet of you, you may wrap the meteor hammer’s chain around part of your body, such as your shoulder, neck or thigh while swirling the hammer end around, confounding your target and giving you advantage on your next attack roll with the weapon.
- Other creatures provoke an opportunity attack from you when they enter your reach.
Whatever level you achieve the initial feat on, after four levels of Hammer Master the user will be granted Meteor Hammer Supreme Master with the additional following benefits:
You have learned the secret of the hidden blades and the hammer is now spiked and bladed. The weapon now does 1d8 bludgeoning, 1d4 piercing, and 1d6 slashing damage due to your proficiency with the weapon.
- You can learn one maneuver of the Battle Master archetype from the following list, which you can perform while wielding a meteor hammer. Disarming Attack, Distracting Strike, Pushing Attack, Sweeping Attack and Trip Attack*. If a maneuver requires your target to make a saving throw to resist the maneuver’s effects, the saving throw DC equals 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice).
Improved Choking attack - On an attack roll of 19, or 20, the attacker can choose to "strangle" the opponent by wrapping the chain around their neck regardless of the creature's AC. This move does not deal initial damage, however, at the start of each subsequent round, the strangled victim takes 1d4+attacker level suffocation damage and is considered prone. This damage increases by 1d4 for each round the victim is strangled. At the start of each of its turns, the strangled opponent may make a STR save of DC=10+prof+STR of the attacker. They continue to take the suffocation damage at the start of each round the save is failed. The creature must be of size large or smaller. Undead and other creatures that do not breathe do not take the suffocation damage but can still be rendered prone until a successful save.
