Mark of the Mant-i Striker Tattoo(Dex)

As a Bonus Action, you can attack with a projection of the tattoo. It is a melee Unarmed Attack and uses your reach. You are proficient with it, and you add your Dexterity modifier to its attack roll. It deals 1d12 + your Dexterity modifier piercing damage plus 1d4 Fire damage. You can’t use this property again until you finish a short or long rest. In addition, if a Decapodian would be hostile toward you at the start of an encounter and this tattoo is visible, the Decapodian is instead indifferent.
