Excellent (EXC): Only if the box configuration includes Excellent option roll index. When present, rolls +1–+3 excellent options with probabilities per ItemOptionRate.txt.

Skill: Only if the box configuration enables Skill option. Grants the item its native attack/magic skill when activated (typically 50%+ chance for common items).
