The symbols Rita found were advanced magical glyphs used for designing equipment requirements. These glyphs stabilize and balance the magic within equipment, allowing it to carry more attributes and possess superior stats. Regular equipment isn't even eligible to use them—only Level 10 purple-grade items might qualify.
However, these glyphs could also serve other purposes. For example, enchanters and tailors often use them to conceal or protect valuables. By setting specific visibility thresholds, items under their protection remain hidden unless the required conditions are met.
The glyphs Rita found had the following requirements:
Divine Gift Rank: S True Strength > 80 True Intelligence > 80 True Agility > 80 True Constitution > 80
This was a trap designed just for her. It fit perfectly, like a hand in a glove.
