What is the rainbow Soul Crystal (Bound) in Aion 2?

Soul Crystal (Bound) is Aion 2's rainbow wildcard crystal. It counts as any family's color in Genus Insight, so it can replace red, green, blue, yellow or light blue crystals. Each pet collection milestone pays 100, about 1,700 in total, and it can't be traded.

Each pet family in Aion 2 has its own Soul Crystal color, but the rainbow one, Soul Crystal (Bound), works on every board. That makes it the most flexible crystal you own. The main source is the pet collection: each of the 17 milestones pays 100, which adds up to about 1,700. Level 45 growth dungeons such as Fafnite Amphitheater and Silent Graveyard are reported to drop wildcards at about 5.8%. Like all Soul Crystals it's bound, so you can't buy or sell it. Spend it where you have no other option first: the Special board, whose light blue crystals don't drop from field monsters. For Fera, Natura, Cogni and Varian, farm their own colors from monsters and keep wildcards as a top-up for the board your build cares about most.

Where to spend wildcards first

  1. Special board: no field drops, so wildcards are the main fuel.
  2. The family your build relies on, when you're a few crystals short of a lock you want.
  3. Never on rerolls you could pay for with farmed Fera, Natura, Cogni or Varian crystals.

A full 8-slot lock costs 396 crystals. Your entire milestone wildcard pile covers about four of those, so plan your locks before you spend.
