Merthuvial

Adamantine Short Sword (Martial Light Melee, 1d6 piercing, 18-20/x2)

Legacy Item

As a Legacy Item, Merthuvial possesses special abilities that cannot be accessed without special rituals. These abilities are unlocked based on the wielder's level, up to the maximum level allowed by the highest completed ritual.

Rituals

King's Gift: To be granted the powers of Merthuvial, you must take rightful ownership of the weapon. In order to do so, it must be given freely and willingly by its current rightful owner. If no such owner lives, then an attuning ritual must be performed. This attuning ritual bears a material cost of 5,000gp and takes 3 days of uninterrupted time (save to eat and sleep) to complete. Regardless of how ownership is acquired, a character must be of either Lawful Neutral or Good alignment. Once you are the sword's rightful owner, you are granted Merthuvial's abilities up to 5th level.
Know the Pain: To further unlock Merthuvial's powers, you must understand the pain that those who fight for you feel. While engaged in mortal combat, you must allow a foe to strike you. That foe automatically scores a critical hit on its next attack. Once completed, you are granted Merthuvial's abilities up to 10th level.
A River to Your People: As a leader, the needs of the people come before the needs of the self. To achieve the next level of control over Merthuvial, this must be demonstrated. A significant material sacrifice must be made by you for the benefit of a group of people over which you are in a leadership role. The sacrifice must be of your own personal material wealth (if the sacrifice is from a communal pool, only your personal stake in it is counted), and must be valued at or above 1,000gp per level attained. The sacrifice of this wealth cannot benefit you directly, and must directly and significantly benefit those it is given to. Upon doing so, you are granted Merthuvial's abilities up to 15th level
Unite the People: A true leader brings people together in times of hardship, strengthening them through unity. You must forge an alliance between two or more disparate groups of people in order to unite them against a common foe. You must then aid in protecting them from that foe until the danger is passed. Once done, you are granted Merthuvial's abilities up to 20th level.

Wisdom of Kings (Su): At 14th level, Merthuvial grants you a +2 Wisdom bonus while you carry it.
King's fury (Su): Starting at 15th level, Once per day you can make a special attack against an evil-aligned opponent.

Fortitude of Kings (Su): At 17th level, Merthuvial grants you a +2 Constitution bonus while you carry it.

A jet black blade supported by a plain, yet clearly masterfully crafted hilt with a single large pearl set in its pommel, Merthuvial looks as though it may well have been forged only yesterday, though its craftsmanship harks back to the dwarven empire of old.
