  • Arguably one of the hardest Future 9+ charts, even compared to lower 10s. The main reason for this is a combination of fast arcs and the ending, using some patterns similar to those in Axium Crisis, one of the hardest 10+ songs. Moreover, it requires players to master the "2132312" and "2312132" technique for the ending. It is more helpful to learn the ending pattern by practicing its counterpart Axium Crisis rather than in Nhelv itself due to higher visibility of the pattern in Axium Crisis.
  • Also, the timing can be annoying for beginners. In the verse, it requires the players to master the irregular rhythm, alternating zigzag Arcs as well as hand-crossing. Knowing which hand should be in which place is the key to deal with the hand-crossing. Watching videos where notes are audible as hand taps as well as proper calibration, can aid in dealing with the other issues. Alternating zigzag Arcs can also be practiced in Axium Crisis.
