5 Posts of concentration, each hit reducing concentration meter by 1 rather than a reset.
Nexon calls out to himself over numerous timelines, linking his mind to theirs for a short period of time. In this short period of time he charges at the opponent and teleports them inside of his pocket dimension, one shared across all timelines. While they are trapped inside, small portals to this dimension pop-up, each one being a different Nexon across the timelines, to hit the opponent. The opponent is hit 20 times , twice by 10 different Nexons. This adds up to 5.5x the user's STR stat plus their current FOC stat. However the damage is not dealt until the opponent is released from the pocket dimension, where every hit hits at the same time again.
Mechanically this only counts as one hit at 5.5x STR plus his FOC at the time.
