I have obtained both The Spirit of Fire and Amidamaru
Spirit of fire: A kami class spirit who feeds off furyoku at an incredible rate. This spirit is unaffected by elemental strikes,hitting this Spirit with an element or chakra will result in absorption of it's power. This spirit may freely act on it's own. Like all kami class spirits,It is able to eat other spirits and Grow in power.
Oversoul form: After fighting with Hao, Zeik's spirit of fire obtaining a more Hellfirey look. It is now covered in a thick coat of magma and razor sharp claws.
Spirit control form: In this form Zeik will use one of his blades as a medium,allowing him to use some of the powers of the fire spirit without the massive chakra drain.
Amidamaru: A regular spirit with an unseemly high amount of furyoku. Amidamaru only has healing properties,but this effect drains his power not my own,using his healing factor cause his over power to drop.
Spirit control form: In this form Zeik can tap into Amidamaru power and healing factor. No other abilities are added to zeik
Duel medium:instead of using Amidamaru Oversoul technique,Zeik prefers to use his duel medium. Using two of his swords as a medium for Amidamaru he is able to increase the power of his "spirit control" by leaps and bounds. in this form Zeik may extend and retract the size of his sword at will,with no hindrance to his speed.
