Petra

Petra is a Venus Djinni found in Golden Sun: The Lost Age, and is overall the fourteenth Venus Djinni found, and is thus the seventh Venus Djinni found in The Lost Age.

Location
Petra is found by random encounter in the overworld region of Hesperia in a vertical stretch of forest in the northeastern region of the continent; this region is most easily reached by sailing the ship into the river opening on the northeastern tip of the landmass. Petra then must be battled to be acquired.

As an opponent
Petra has 830 HP, 77 PP, 260 Attack, 79 Defense, 227 Agility, and 26 Luck.

It can use a standard attack as well as cast Quake Sphere, Stone Spire, Mother Gaia, Wild Growth, and Briar.

When felled it yields 937 EXP and 631 coins.

Description
When Set, it increases base HP by 11 and base Defense by 3.

When used, Petra paralyzes the target and making it unable to move for one of its turns, and the user casts this effect first in battle regardless of the agility of allied adepts and enemies.

Analysis
This move has many uses such as using this to deprive a Wonder Bird of one of its three turns and make it easier for other Adepts to KO it before it can launch a powerful attack or flee.

Name Origin
Petra is an abbreviation of the word petrified, which refers to any organic material that is changed to stone (hence the reason the Djinni Petra causes targets to become immobile). The most common case of this is petrified wood.

Interestingly, Petra is also the Greek word for rock. There is yet another Petra, this one an ancient city carved out of the cliffs in Jordan.
