Resonance

Resonance (ふぁんとむ Fantomu) is an advanced Demonic Possession spell.

Description
Resonance allows Dante to seal a demonic soul within themselves in order to use its power. In order for the sealing to be successful, he must balance his own magic and the demon's magic at a 1:1 ration (evenly matched), something which is extremely difficult to do as even a slight deviation from it can cause both souls to be destroyed. The ratio must be kept even in the spells that are being cast. When using this spell, Dante gets covered in a shroud of his chosen demon's aura, obscuring him completely. This spell allows him to use a variety of magics particular to the demon he possesses.

Abilities
Darkness Magic(闇の魔法 Yami no Mahō): Due to having possessed Mephisto, the Phantom of Darkness, Dante has gained a passive affinity to Darkness Magic. He can utilize a variety of spells, both offensive and defensive. In order to prevent himself from using Take Over, Dante had learned to fight using Darkness Magic by tricking and trapping his opponent in it before crushing them.


 * Dark Spark(だあくすぱあく Daaku Supaaku): A mid-level offensive spell that solidifies and condenses darkness. When the spell is launched it looks like lightning, hence the name. It can be used in a variety of ways. So far, Dante has fired it like an arrow and a wave, and shaped it in the form of a tower. The power depends on the magic being used.


 * Void Spear(ヴぃおどすぴあ Voido Supia): Another mid-level spell. Depending on how it is used it can be both offensive and supportive. So far, Dante has used it mostly for a decoy in order to prepare for his other, more destructive spells. Void Spear possesses a homing effect that when launched will chase the target until it hits. The downside is that the longer the spell chases the target the more it weakens until it will eventually disappear.


 * Evil Spinning Top(マゴマ Magoma): As the name suggests, by spinning and at the same time releasing darkness magic from his body he can achieve the visual effect of a spinning top while dealing massive cutting damage to his surroundings. He can either use it while standing still or moving. It can also be used for both defense or offense.
