The first true boss battle you will run into in The Legend of Zelda: Echoes of Wisdom is the Seismic Talus. This big chap is guarding the exit of the Suthorn Ruins, and you’ll be stuck here until you can deal with him.

Suthorn Ruins is the first dungeon in Echoes of Wisdom, and an excellent re-introduction to the kinds of mechanics that make Zelda dungeons special.
