Dim Dragon Plus

The Dim Dragon Plus is an optional boss encounter early in Golden Sun: Dark Dawn. It is an enhanced version of the Dim Dragon, and is fought at the same place as where the Dim Dragon was fought, which is at end of the fourth course of the Psynergy Training Grounds. It is fought every time the Psynergy Training Grounds is repeated with the hard-timer setting in place. Whereas defeating the Dim Dragon for the first time will reward you with the Gate Card from one of the two chests, defeating the Dim Dragon Plus for the first time will reward you with the contents of the other unopened chest, which is a Water of Life.

It can physically attack, use Scary Jinx to set a Death Curse, exhale Pebble Breath and Sizzle Breath to deal surprisingly heavy damage to one Adept, and exhale Gasping Breath for some damage against all Adepts. Sometimes it will go "out of order" for two turns, at the end of which it will perform repairs on itself and heal 35+ HP and then be able to fight normally again.
