This black hat has a red band and a wide razor sharp brim. There is an adamantine ring embedded in the brim that shines in bright light. This hat is most often worn by monks.
Property (attuned): You are proficient with the hat as a weapon, and gain a +2 bonus to attack rolls and damage rolls you make when using the hat as a thrown weapon (1d8 damage, range 30/90) .
If you hit a creature with a thrown Razor Rimmed Hat, you can cause it to ricochet and strike a secondary target in an adjacent square (within 5 feet of the primary target). You immediately make an attack roll against the secondary target, at a -2 penalty. If the attack hits, you deal damage normally.
Once per day you can take an action to roll the hat in a straight line on the ground up to 50 feet, any creature in its path must make a DC 15 Dex save. On a failed save: take 8d6 damage and half on a success.
Returning: You can utter a command to summon the hat, and after making a ranged attack with the hat, you can catch it as a free action. If you do not wish (or are unable) to catch it, it teleports back to your head with no action, or into your hand if you wish.
