Astral Blast and Thunder Mine

Astral Blast and Thunder Mine are Jupiter single-target Psynergies, available to the Page and Apprentice Class series. As such, Isaac (Apprentice), Felix (Apprentice), Garet (Page), and Jenna (Page) can use them if they have enough Jupiter Djinn to be in their respective class series.

Astral Blast
An "attack with celestial force", Astral Blast appears as a group of stars being fired from the user's attack, striking the foe at a distance. In the Page series, Astral Blast is usable by the Page, Illusionist and Enchanter classes; in the Apprentice series, it is usable by the Apprentice, Illusionist and Enchanter classes (note that the latter two classes are different from their counterparts in the Page series). Astral Blast isn't as strong as others like it, such as Heat Wave, but it does serve its job quite well, especially against Venus-based enemies such as Tret. Astral Blast costs 5 PP to use.

Thunder Mine
As all Psynergies like it do, Astral Blast is replaced by the more powerful Thunder Mine after the wielder reaches the Conjurer class (in both series). An "attack with ball lightning", Thunder Mine appears as a large ball of plasma-like energy with a heavy electrical charge slowly crashing into the foe. Unlike other, more commonly used counterpart attacks, such as Diamond Berg, which carry the burden of belonging to a class that has very low Psynergy, Thunder Mine is supported by a somewhat decent supply. Thunder Mine costs 16 PP to use.
