Quartz and orbal arts
In Cold Steel, quartz equipped in an orbment directly enables specific orbal arts, replacing the earlier elemental-value system described in the source. Tactical orbments use installed quartz for a range of effects, including the ability to cast arts.
How it works
The supplied windows do not name a Cold Steel III art, the quartz that enables it, or individual requirements. Choose based on the arts listed for the quartz in game; the evidence supports the general relationship, not a specific build or art recommendation.
When it helps
Match equipped quartz to the orbal arts you want available, using the in-game descriptions.
The tradeoff
The windows establish the system but do not provide specific quartz effects, art requirements, or Cold Steel III slot constraints.
Your next step
Review the equipped quartz and available arts in game before changing the orbment.
