Quartz for stat effects
Quartz installed in a tactical orbment can provide effects, including statistical improvements. The supplied orbment overview says Cold Steel orbments allow multiple quartz affecting the same stat in one orbment, provided the quartz are not identical.
How it works
The evidence does not name individual Cold Steel III quartz or quantify their stat bonuses. Use the in-game quartz descriptions to identify the stat effect and compare the available options; no particular combination is established here.
When it helps
Choose quartz by the stat effects listed in game and the character's needs.
The tradeoff
The supplied windows do not provide named quartz, bonus quantities, or character-specific recommendations.
Your next step
Compare the displayed effects before equipping or replacing quartz.
