Arenir’s Blade Flourish

You enchant yourself with a flood of energy as you begin a series of ever quickening weapons strikes. You may target any number of creatures within range with a single melee weapon attack. This functions as if you took the Attack action against each creature, however, regardless of the number of attacks you may normally be able to take you can only ever make one attack against each targeted creature. Once every chosen creature has been effected the spell ends and you may choose to sheath the weapon as a free action. After being stowed in this way it must be drawn again to be used afterwards.

This spell can be upcast increasing the area affected; 40ft at 5th level, 50ft at 6th, 60ft at 7th, 70ft at 8th, and finally 80ft at 9th.
