Abandoned Mine

The Abandoned Mine (小山の洞窟 Little Mountain Cavern) is a mine rich in Psynergy Stone minerals northeast of the Goma Plateau beyond the Tanglewood. It and the two aforementioned locations comprise the first three-part introductory dungeon to Golden Sun: Dark Dawn, of which this is the last part. It contains the first boss battle in the game, the Tangle Bloom.

Matthew, Karis, Isaac, and Garet must travel to and through the Abandoned Mine in search of Tyrell, who had crashed here while flying the soarwing. They find him unconscious, his energy having been sucked out by a Psynergy Vortex that has appeared here for the first time Isaac can recall, and before they can reach him they are attacked by an enormous plant monster, the Tangle Bloom. They dispatch it fairly easily with Isaac and Garet's experienced help and save Tyrell.

Walkthrough
Head into the mine and use the Psynergy Stone if you need to, then head south through the door. Head east now until you're stopped by the broken track, use Growth on the small plant so you can continue upwards. Head down the stairs to the east and continue onwards to reach another part of the cave.

In here, everyone will shout for Tyrell with no luck. Garet will throw around some fireballs to try to light up the place, until they find one of those Psynergy Vortexes we learned about. You can also see Tyrell nearby, unconscious due to having no psynergy. Isaac and Garet will also try to explain the reasons behind the vortex's, which doesn't help Tyrell very much.

Head around the path, around the vines and past the vortex( you cannot touch it). Use your Growth psynergy on the plant, and now you can walk around and climb down it. Get near the flower and hit it with a fireball. Prepare for a simple Boss Bight!

After the battle, run over to Tyrell to start another scene. Isaac and Garet will infuse some psynergy to make Tyrell wake up, and after all the verbal lashing that follows, the adults will task us with getting new materials for another soarwing.

You can use the northern exit for a shortcut that leads to where the soarwing crashed, so you can salvage it.
