The Ring of Sight gives a Perception bonus by the following formula: PER = PER + WIS

That is, the wearer's Perception attribute is increased by the Wisdom attribute.

While worn only, the ring of light also gives the wearer the following spells:

• Analyze Light
• Zoom
• Night Vision
• Detect Invisible

Spells are cast according to the normal spell rules, except that prerequisites do not apply and the wearer effectively “knows” the spell.
