Aetheric Armaggedon

«Aetheric Armaggedon» (エーテルヰチ・ハルマゲドン) is a unique, ultra high-level, One-Handed Sword-category Sword Skill in Spell Blade Online and Project Alicization. In Spell Blade Online, it is unlocked after getting Sacred Cross's proficiency level to 900.

Description
«Aetheric Armaggedon» consists of a total of ten strikes. The first is a heavy slash from the top right to the bottom left before immediately rebounding the blade and slashing back in the direction it came, carving a deformed "X". The user then pulls back the blade and slashes from the bottom right to the top left and spins the blade over their head to land a horizontal slash before rebounding and slashing back, forming another deformed "X". The user makes a full-power downward slash from the top and draws the blade back to make a full-power thrust. The user then slashes from the top left to the bottom right and spins before repeating that slash then corkscrewing to make a slightly slanted right to left slash.

The skill is conducted extremely fast and the final three strikes will combine to unleash an extra, eleventh hit that consists of an energy wave with a magical damage property of 20% of both wind and water (the equivalent of ice) plus 60% holy.

The skill is activated by holding the sword in the right hand normally with the blade pointing outwards before bringing it towards the center from the bottom in a full circle and stopping at the center, in an ' en garde ' position.
