Breath of Fire: Dragon Quarter Secrets (PS2)

Breath of Fire: Dragon Quarter, known in Japan as Breath of Fire V: Dragon Quarter, is the fifth RPG in the Breath of Fire series. An unspecified amount of time before the game begins, humanity fled the desolate surface world to the underground in order to survive. Now, the world lies in a state of turmoil; polluted and stagnant, only the upper classes are able to escape to higher levels with better air. The game follows Ryu, a low-level citizen, who rebels against his government in order to save the life of Nina, who is unable to survive underground, due to an experimental surgery performed on her in order to convert her into an air purification machine. According to Breath of Fire tradition, dragons play a large role in Dragon Quarter, and Ryu himself is able to transform into a dragon.

Despite this tradition, however, the main influence of Dragons is felt in the storyline of the game and not the gameplay - unlike every other installment, Ryu can only transform into one Dragon form. The focus of the story is on Ryu's escape to the surface with Nina, accompanied by the ever-watchful Lin. A majority of the game simply focuses on Ryu and the company's ascent from over a kilometer below the surface to ground level, traversing dark underground passageways and fending off the encounters they find. On the lowest levels, one can find those with low D-ratios; as one ascends the levels, the D-ratio of the inhabitants increases.

Secrets

Huge zenny early game.
In the ice cave, you'll find a monster called "jack-box" This monster increases the amount of Zenny it drops upon defeat every time it is hit. Unfortunately, every time it takes a turn, it reduces its zenny counter to zero.

The trick for this one is, SKIP YOUR FIRST TURN. Have everybody charge up and wait for the box to make his move. On turn two, unload with level 1 attacks. A party of level 16s can easily kill it in one turn. And massing level 1 attacks will make it drop an astounding 60,000 zenny, as opposed to the 3,000 you'd have throughout normal progression through the game.

No shield for Bosch
Before Bosch leaves your party, equip explosion from the skill menu on to Bosch's shield. When you meet him again, he will lose his shield during battle!
