Whiplash

Whiplash (ウィップラッシュ) is a Jupiter Psynergy featured in Golden Sun: The Lost Age. It is notable for being the only offensive Psynergy available to all stages of the class.

Basic description
Whiplash is an offensive, single-target Psynergy that is Attack-dependent, meaning characters with higher Attack ratings will deal more damage with these attacks. In addition, the caster's Jupiter Power and the target's Defense and Jupiter Resistance all factor into the damage dealt.

Visually, Whiplash features the caster wielding a purple energy whip, which lashes out at the target.

Availability
Whiplash is unique to the Tamer class series, an Item-dependent class accessed by equipping the Trainer's Whip to an appropriate Adept. Since the Trainer's Whip is only found in The Lost Age, Whiplash is limited to the eight playable Adepts in that game. Whiplash is learned at level 10.

Analysis
General: Whiplash is the only Psynergy available to the Tamer with a damage multiplier rather than a set amount of added damage. However, the lower damage multiplier means that early on, the Tamer's other Attack-based moves, will do more damage. Though Whiplash will grow stronger as Attack rises, it will become severely outclassed by Ghost Soldier, which adds a whopping 170 points of damage and can ignore half of the target's Defense. Whiplash's main benefits are its low PP cost, a boon considering the Tamer's abysmal PP pool, as well as its availability. Since Whiplash is the only offensive Psynergy available to all stages of the Tamer class, it can be a reliable move in a situation where changes between class stages is expected.
