Bahamut's Fury Tattoo

While this tattoo is applied on your skin, you are resistant to nonmagical bludgeoning, piercing, and slashing damage.

As a bonus action, you can manifest a broken spear known as Lakas that looks worn. You gain a +3 bonus to attack and damage rolls made with this magic weapon, with which you are proficient. Instead of a spear’s normal piercing damage, Lakas deals piercing damage equal to 1d8 plus your ability modifier on a hit, has the versatile (1d10) property, and ignores resistance to piercing damage. You can use a bonus action to dismiss the spear.

Unstoppable: This spear allows for the bypassing of magical barriers. When encountering a magical barrier (Shield, Resilient Sphere, Forcecage, etc.), making an attack with Lakas against it has a chance to shatter the spell. Make an attack roll against the caster, who makes a spell attack roll. On your success, the spell is shattered, the spell slot used and dispelled in violent fashion. On a failure, the spell resolves unimpeded.

Reforge. As an action, you can raise Lakas to the heavens and magically restore it to its former glory for the next minute. For the duration, the spear sheds bright light in a 30-foot radius and dim light for an additional 30 feet. When you hit a creature with a weapon attack using Lakas, that creature takes an extra 3d6 piercing damage. Once used, this property of the tattoo can’t be used again until the next dawn.

While Lakas is reforged, you can activate the Antispell and Shields Up properties, After you activate one of these properties, roll a d6. On a 1, you can’t activate either property again until the next dawn.

Antispell. You can cast the counterspell spell at will (+5 spellcasting ability modifier).

Shields Up. As a reaction when a creature within 30 feet of you that you can see is hit by an attack, you can grant it a protective magical shield that rests on its forearm (unless it is already wearing a shield). The creature gains a +2 bonus to its AC until the start of its next turn. You can declare this after the attack die is rolled but before the action is resolved.

Divine Tattoo. You can only attune to this tattoo if you are attuned to no more than one other magic item. If you attune to more than one other magic item while you are attuned to this tattoo, your attunement to this tattoo immediately ends.

Lore to edit? Bahamut values valor and honor, and those who show restraint as well as mercy to enemies they have overcome. The great Qinju, mighty general in the ancient kingdom of Talin*, was one such warrior. Qinju reined in the bloodlust of his first emperor, and nurtured their more tolerable and fair-minded heir. Qinju’s efforts resulted in prosperity throughout the kingdom and treaties with neighboring lands. He established a generation of soldiers worthy of their own tales. In honor of his labor, the aging general was visited by Bahamut who bestowed special markings upon him to enhance his abilities and prolong his righteous influence over Talin. The lessons of General Qinju are still applied in the training of soldiers, guards, and knights all over the world to this day.

*Talin was one of the "kingdoms" that the First Iridescent Empress conquered after the Cataclysm

Produced by a special needle, this magic tattoo was designed through divine inspiration in honor of the Platinum Dragon, Bahamut.
