Why are cube user unpopular ?
1. Hard to craft cube. Unlike another series, the only way to craft it is throwing massive essence to window ( crafting costs more than 1b )
2. Cube weapon cant active any accessories set effect.
3. VALERON SERIES HASNT "CUBE"

Idea:
1. Create Valeron Cube (37 AR)
2. Merge Cube with Spell Book (cube will be fake weapon like Mireille's Kats sword or Bryan's hammer)
