Whirlwind style attack. Once per short rest, and while maintaining concentration. Use your Action and continued concentration to swing both the chain and blade, striking multiple creatures that you can see within 10ft of you.

Add your Acrobatics skill modifier to each roll to hit. Each successful hit against the target's AC deals 1d4 + your Strength modifier.

The number of strikes is equal to your Dexterity modifier multiplied by the number of chain blades being used for the attack (typically 2), and may hit the same target or multiple targets within range. Both the blade and chain must be available to perform this action for each chain blade being used, so not being used to restrain, incapacitate, or grapple a creature.
