Gaia No Buin | The Staff of Gaia
Type: Weapon
Rank: S-Rank
Range: Short
Chakra: N/A
Damage: N/A
Description:
The staff of Gaia, goddess protector of Earth, stolen by a special human for whom se had fell in love. The staff is covered in several ancient Kanji inscriptions and is about 1.7m long, 4 cms thick and made of sacred wood and a special unknown metal which makes it indestructible. The staff itself can channel Katon, Doton and Mokuton chakras and is a formidable hand to hand weapon. As the weapon of a God, no human can grasp its powers fully but the staff is known to have responded to some unique jutsu, a fact that has been related to the kanji inscriptions but is yet to be fully explained.
Abilities:
-Indestructible
-Doton: Domu | Earth Release: Iron Skin jutsu gets 2 Ranks in strength when used, making one almost indestructible to physical attacks.
-Katon: Karyu Endan | Fire Style: Dragon Flame Bomb jutsu gets 2 Ranks in strength when used, outputting a higher amount of fire.
-Kyousei Mokuton No Jutsu | Greater Wood Style Technique can be made out of the Staff's wood.
-Staff can dispel a Katon jutsu, disrupt a Doton jutsu or stop a Mokuton jutsu up to B-Rank 2 times per battle (this is done by the user channeling his Katon, Doton or Mokuton chakra into the staff and hitting the jutsu with it, which disrupts, dispels or stops the jutsu) and/or dispel/disrupt/stop 1 complete A-Rank Katon, Doton or Mokuton jutsu once per battle (with the same principle).
Resctrictions:
-All abilities of the staff count towards the move count and don't require hand seals if the user is holding the staff on his hands.
-The kanji's on the staff glow when chakra is channeled into it or its abilities used.
-If user is hit by lightning while holding the staff in his hands he'll receive a +20 damage penalty due to the staffs inherent Earth and Wood affinities.
-When used to counter 1 B-Rank technique it can only be used again to counter another B-Rank.
-While holding the staff in his hands, the user can't channel lightning jutsu.
-To wield the staffs abilities the user must have it with him either in hand or strapped to his back.
-Requires Wood Training and Bio to use the Wood Ability but not to wield the staff.
-The staff can only be wielded by Scorps; is someone else tries to wield the staff it will become 10 tons heavy and impossible to lift or wield.
