Tret

Tret is a faerie tree found in Kolima Forest, and is fought as one of the bosses in Golden Sun.

In Golden Sun, he is a guardian of the forest. Lady McCoy's yearning for a palace of her own drove her husband to commission Kolima's lumberjacks to bring down all the trees needed for it. Ultimately, one of the lumberjacks even took an axe to Tret himself, at about the same time Psynergy Stones rained down from Mt. Aleph's eruption. Tret was struck by such a stone while in a state of rage that Kolima, which until then had respected him, would try to cut him down. With the glamour (i.e. faerie magic) abilities that the stone gave him, Tret turned the entire population of Kolima into trees. Tret had still been cut so badly that he was slowly dying, and when he died, so would the entire forest bound to him. Thus, the cursed humans would die as well. When the party enters Tret's forest or the town of Kolima for the first time, they are attacked by Tret's glamour, which induces a cutscene.

In battle, he resembles a bald, masculine head that has a blue flame surrounding it. Tret mainly uses plant-based Psynergy like Thorn and Growth, but may every so often use a physical attack. Useful Psynergy to use upon him is Mars Psynergy and the Ragnarok Psynergy.

After the battle, Tret attempts to reverse his curse, his rage finally becalmed. However, he is too weak to effect the reversion. The party needs to save him by using some Water of Hermes on him from the fountain at Mercury Lighthouse.

To revive him, the party needs to get water from the lighthouse and backtrack to Tret in order to apply it. Once he is revived, the curse is undone, and more water can be taken and used on the party to recover all HP to one character.

Tret Tree
Within Tret, a new dungeon reveals itself after climbing up a path of vines and entering a hole above Tret's face. Inside, it is possible to climb up new vines to reach a higher floor or climb up branches instead. There are various holes with cobwebs on some floors. Fresh looking leaves will begin to fray once stepped on. Fraying leaves will completely break apart if stepped upon and Isaac will fall down to the floor below. Outside, on the branches, the Jupiter Djinni Breeze can be found. Upon reaching the topmost branch, it is possible to find a leaf at the centre of the tree which will then break and you will fall through the holes seen on every floor. After falling through the holes and landing on the bottom floor of Tret, the player will then find another Tret face on a nearby wall. Tret awakens and tells Isaac and company they have not found his kindly side, as they had hoped. He then engages them in battle.

Tret has 170 HP and is weak to Mars Psynergy. Upon his defeat, he will reward you with 226 EXP, 700 coins and a Psy Crystal. He has a normal attack, as well as Venus Psynergy, such as Thorn, Growth and Quake. He also casts Sleep Star, which has the possibility of sending up to three targets to sleep, so having Elixirs on hand is recommended.
