Demon Night and Thorny Grave

Demon Night (ひゃっきやこう, Demons' Nightly March) and Thorny Grave (おどろおくり, Thorny Grave) are a pair of offensive Venus Psynergies featured in the that are functionally identical but have different levels of power. Demon Night was introduced in, while Thorny Grave was introduced in.

Basic Description
Demon Night and Thorny Grave are ranged Psynergies. The final amount of damage is determined by comparing the user's Venus Power to the target's Venus Resistance and using the difference to modify the base power of the particular Psynergy in use.

In Golden Sun and The Lost Age, Demon Night features a group of purple-colored spirits attacking the enemy. The spirits are small in size, but relatively numerous. In Dark Dawn, the caster will plunge their weapon into the ground. Meanwhile, the surrounding area will grow dark with a blue mist lingering about. Multiple blue spirits will emerge from the ground to attack the foe.

Thorny Night retains the general visual characteristics, but with a few key differences. In The Lost Age, the summoned spirits are larger in size, and are colored a dual purple/black. Dark Dawn's version is extremely similar to Demon Night, but features larger and more numerous spirits.

Availability
Demon Night and Thorny Grave are unique to the Samurai class series, meaning that only Venus and Mars Adepts have access to the series. The exception to the rule is the Venus Adept Himi, who cannot access the class. Similarly to the Ragnarok series, Thorny Grave is a replacement for Demon Night as higher classes are reached. Demon Night is available to the Samurai stage, while Thorny Grave is available to the Ronin stage of the class. Both Psynergies can be learned at Level 18, with only the Adept's class determining which Psynergy is learned.

Analysis
General: While useful in theory, the Demon Night series is often overlooked in favor of the other numerous Psynergies available to the series. : Demon Night will be weaker than Rockfall, which will generally be available to the typical endgame party. Generally, the Samurai will be used more for its overall sturdiness and array of buffing Psynergies, and thus, Demon Night will see little use.

' and Golden Sun: Dark Dawn:' While Demon Night's usage will be similar to its previous appearance, Thorny Grave is a viable, if overlooked option. Thorny Grave has the distinction of being the strongest multi-target Psynergy available to the Ronin. However, it will pale in comparison to the raw power of Epicenter, and the strength and reliability of Quick Strike.
