Hello,
Barcumbuk is a custom creature in AV's seventh level.
He has and ability I don't know how to interpret.
Furious Fusillade The erinys hovers in place if they are flying and fires one arrow at any number of creatures in a 30‑foot cone. Each attack is rolled separately. This counts as one attack for the purpose of the erinys’s multiple attack penalty.
He doesn't have a missile attack that uses arrows and arrows by themselves have no attack and damage values.
He has the ranged attak of a Flaming Light Hammer +19 / +15 / +11 (agile, evil, fire, magical, thrown 20 feet), Damage 1d6+6 bludgeoning plus 1d6 evil and 1d6 fire.
My inclination is to read the stat block as Furious Fusillade using the Flaming Light Hammer attack.
Is this correct? Is there better option?
Thank you.
