Revelations
Trick Weapon (Cleaver, Whip), Very Rare (Requires Attunement by a Creature with a Strength of 15 or Higher)
Cost: 40,000 gp
Base Items: Cleaver, Whip
Made of an unknown metal that mixes blood and steel, this ghastly sword is studded with dozens of eyes from various creatures that stare hungrily at all who are confronted with it. Only a competent hunter can wield a weapon of such weight, but armed with it, they will never lose sight of their prey and will never be caught in an ambush. Such a dangerous weapon should only be used with the utmost caution. You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon. While attuned to it, your sight improves as your vision starts echoing with that of the blade. While holding Revelations, you gain the following benefits:
Trick Weapon
As a Bonus Action, you can switch between the Transformed and Untransformed states of this weapon. In its Untransformed state, the weapon is a Cleaver studded with eyeballs. In its Transformed state, the weapon is a Whip composed of metal shards held together by a sinew of blood and flesh.
Untransformed
When you hit a creature with this Cleaver, you curse them for the next hour. For the duration, you gain a +1 bonus to damage rolls made with the weapon against the target, attack rolls you make with the weapon against the cursed target score a Critical Hit on a roll of 19 or 20 on the d20, and you have Advantage on any Wisdom (Perception or Survival) check you make to find the target. The curse ends early if you transform the weapon or if you have the Unconscious condition.
Transformed
This Whip deals 1d6 Slashing damage on a hit, has the Versatile (1d8) property, but does not have the Finesse property. Once on each of your turns when you hit a creature with this weapon, you can attempt to crush them under the weight of the Whip. The target must succeed on a Strength saving throw (DC equals 8 plus your Strength modifier and your Proficiency Bonus) or take 1d6 Slashing damage and have the Prone condition.
Curse: Devour Sight
While attuned to this weapon, your sight deteriorates rapidly. For each five days that pass, you gain a permanent -1 penalty to all Wisdom (Perception) checks made using your sight. When this penalty reaches -5, your eyes rot and melt out. You have the Blinded condition, as two new eyes appear on the blade. The sword's curse is insidious: while you remain attuned to the weapon, you do not suffer the penalty to your Perception checks, and you do not realize that your sight is worsening. The blade's influence makes you perceive the world in a clearer light.
