Oski's Weapon

Weapon name: Majoris Arcanis
Weapon rank: Transcender tier 1
Description: Majoris Arcanis is a special item of significant history for the Gods. Majoris is a transplant-able God weapon that takes the form of a solid gold eye though it is not gold it is made of pure Aether. Hidden by his eye patch, when revealed the golden eye gives of a massive amount of light and power which causes great winds to exude from Oski's body though this is merely aesthetic. So far Oski only has the power to call forth of Contract of the Gods which is a massive godly contract written in the language of the Gods that only they can read. The Contract of the Gods has the ability to grant great power as well as replace things with other things.
Ability/Spell name: Offer of Arcanis
Description: Upon unleashing the power of Majoris Arcanis, Oski is able to use its power to increase his own power. Majoris Arcanis will allow Oski to sacrifice one of his body parts or one of his senses in order to gain power equal to one tier higher than his own for the duration of its activation. When the contract of Majoris Arcanis is complete and a sense of limb has been sacrificed, Oski will glow with the golden light known as Aether and be empowered, becoming a dangerous opponent.
Duration and Cooldown: 5 post duration/7 post cooldown.
Strength: Once activated, Oski gains power out side of his actual limit. Oski gains +1 to tier rank allowing him to become even stronger, faster and overall more resilient as well as raising the power of his abilities by +1 tier.
Weakness: Because of the great boost in power that the user receives by using Majoris Arcanis, it requires a great deal of sacrifice to be allowed this power. The user must give up the use of one of their limbs or one of their five senses during the duration of this ability. If the limb or sense is already not usable then Oski must give up a usable limb or sense. (example: If Oski is blinded already, he cannot give up his eye sight, he must give up something else.)

What about when you reach max rank? Is the ability still going to increase your power equivalent to a full rank, or will it give another form of boost?

Majoris Arcanis will have to be updated for limit breaks once we get there however that wont be until we all get 800 + posts and like 4.5 mil gold

Approved!

added more to the weakness of the ability anyway: If the limb or sense is already not usable then Oski must give up a usable limb or sense. (example: If Oski is blinded already, he cannot give up his eye sight, he must give up something else.)
