Vasu

Vasu is a turban-wearing Arabian-esque man who is the owner of Vasu Jewelers in both The Legend of Zelda: Oracle of Seasons and Oracle of Ages. He appraises any Magical Rings Link finds for 20 Rupees (aside from the first, which is free). New rings are added to Link's list, while Vasu buys duplicates for 30 Rupees regardless of rarity. He also provides Link with the level 1 Ring Box upon meeting him, and at various points gives him the Friendship Ring, Slayer's Ring, Wealth Ring, and 100th Ring. In Oracle of Seasons, he also hides a ring in a high spot in Spool Swamp.
