North Cave

5 ore boulders and one healing boulder are here. Breaking one takes a Pickaxe or the Ultra Pickaxe. An ore boulder gives one of the eight elemental shards at random, or more with the Ultra Pickaxe. A healing boulder restores your whole party instead.

A mined boulder comes back after 900 to 1,200 seconds of play, or 600 to 900 for ore with the Miner's Goggles.

Tamer 52 stands here and battles you on sight; their page has their parties and rematches.
