Editing Nine Circles Levels (section)

===Decoration===
*'''Diamond block structuring must account for AT LEAST 50% of the decoration style while the wave game-mode is active:''' All current Nine Circles Demons use diamond blocks to form wave corridors. These blocks are angled at 45° or 60° to align with standard or mini-wave trajectories. Unlike levels like [[ZAPHKIEL]], where wave corridors use angled lines but lack diamond blocks. Nine Circles structuring requires diamond blocks to extend fully to level boundaries (floor/ceiling). Compared to non-diamond structuring styles:
**'''Spike and pillar structuring:''' Uses spikes and vertical pillars, found during sections 28% to 35% of [[The Golden]] and 23% to 34% of Hatred.
**'''Slanted pillar structuring:''' Uses diagonally aligned pillars, found during sections 61% to 87% of [[Cold Sweat]] and 6% to 15%, 75% to 84% of [[Cataclysm]].
**'''Rectangular block structuring:''' Relies on rectangular blocks with slanted corridor lines, found in all wave sections of ZAPHKIEL and 63 to 67% of [[Slaughterhouse]].
*'''The concentric flashing effect appears on the surrounding structuring for at least 50% of the time that the wave game-mode is active:''' Concentric flashing is explained as follows:

*'''Figure 1''' shows five circles all with the same centre but different sizes. Concentric is defined as 'of or denoting circles, arcs, or other shapes which share the same centre, the larger often completely surrounding the smaller.' In this formation, bars of space are created between the circles.
*'''Figure 2''' shows concentric diamonds in the 1.9 Nine Circles style.
*'''Figure 3''' details the following sequence:
**Bars 1–4 cycle ON/OFF in order (1→2→3→4→1…).
**Flashing can reverse (4→3→2→1→4…).
**The pattern must flow repetitively inward (OUT→IN) or outward (IN→OUT).
**All rated Nine Circles levels include this effect.
The flashing can occur in the opposite direction, with bar 4 flashing first and bar 1 last. The flashing on the object must have a repetitive IN-to-OUT or OUT-to-IN direction, with OUT being the outer edge of the block and IN being the centre of the block. The concentric flashing does NOT need to cover the entire structure (e.g. Super Mario Wave or Cat Planet). Each current-rated Nine Circles level features this effect.
