Punji Psynergy series

Punji, Punji Trap , and Punji Strike are a series of Venus Psynergies featured throughout the Golden Sun series. The series seems to be similar in nature to the Thorn Psynergy series.

Basic Description
Punji, Punji Trap, and Punji Strike are offensive, ranged Psynergies. The overall power of each stage is determined by comparing the user's Venus Power and the target's Venus Resistance, and multiplying the resultant ratio by the base power of the Psynergy being used.

Visually, the Punji series features a group of bamboo shoots quickly sprouting up beneath the targets. The number and size of the bamboo shoots increases with each successive stage. Its unique visuals in Golden Sun and are in contrast to the other ranged series of the Ninja class, which shared visuals with other Psynergy series. In Dark Dawn, the series was preceded by a unique casting animation, which featured golden symbols emerging from a similarly colored scroll that formed around the caster.

Availability
The Punji series is unique to the Ninja class series, available to Venus and Mars Adepts. Access to the class requires Jupiter Djinn and Djinn of the element symbiotic to the Adept's own element. Punji is learned at Level 4, while Punji Trap is learned at Level 15, and Punji Strike is learned at Level 36.

Analysis
General: The Punji series is the only Power-based Venus series available to the Ninja class and also is the second strongest Power-based series available to the Ninja class, after the Thunderclap Psynergy series. The series is available fairly early on, with Punji Strike available at Level 36, and is fairly cheap in terms of Psynergy cost. As a Venus-based offense, it can be outperformed by the Attack-based Annihilation, but is still useful for hitting multiple targets.

Cultural references
The names of the series appear to come from the Punji Stick, a style of trap that used upright spikes of wood or bamboo. The spikes would be hidden in areas commonly passed through by enemies, and were designed to wound rather than kill.
