How can i find Mavin's ring needed by oracles on the cave to seacond town ?
And what to do after toad shaman opened the secret door ? Where i supposed to go ?
Please help !

The Mavin ring is in the Tomb of Nivius, located in the Tomb of Heroes, which is in the Crypt. To reach the Tomb of Heroes, you must pass through either the Wizard's or Warrior's Firepits area, and the Asylum.

Well, Shinwiki opens a door... so what do you do? Go through it! Walk through the passage. Come out of passage. Explore the area. Come on, haven't you been listening to what Shinwiki wants you to do?
