Gale Psynergy series

Gale, Typhoon, and Hurricane are a series of Jupiter attack Psynergy featured in both games. The Gale techniques are all Jupiter aligned. Gale is also useable like Whirlwind outside of battle. It is available to the NInja class series. Hence, all of the adepts in your party, except for Mia and Piers, can use this series of Psynergy.

This Psynergy series is nearly identical to the Whirlwind Psynergy series.

Typhoon: “Attack with the wind's might.”: This costs 13 Psynergy Points, has a base power of 76, and has a range of five targets. Two large whirlwinds with minor electric charges spin through the enemy party. It is available at level 18.

Analysis
The Gale psynergy series is costs slightly less than the whirlwind series and it's power is slightly less as a result. Gale's overall usefulness is limited because it is not even the strongest Jupiter psynergy that a ninja has, that honor would go to the Thunderclap Psynergy Series so Gale's usefulness is limited to the levels where the Ninja has this power but not the latest Thunderclap spell.

Gale as a Utility Psynergy
Gale is a Psynergy that can be used in the field to blow away green bushes. It is pretty much completely identical to the Whirlwind Psynergy except in name and the fact it costs fewer PP.
