The Ultimate Spirit Arm (究極の霊装, Kyūkyoku no reisō) is Lóni Drauvnil's final masterpiece, said to surpass even the E-Bomb.
Appearance
This type of spirit arm is a huge humanoid machine made of steel, with surfaces covered in seal rites that resemble electronic circuits.
This giant robot has a spirit arm unit mounted on its shoulder, which is a concept-writing spirit arm (概念的に書き替える霊装, Gainenteki ni kaki kaeru reisō) capable of rewriting an opponent's concept by altering the concept within a materialized fossil of an Old Deus using seal rites.
