OC's Curse Technique

Curse Technique: Arithmetic

Curse Technique Lapse: Subtraction: can gradually subtract the amount of curse energy that is targeted.  It can also target physical objects and concepts that the user is aware of.

Cursed Technique Lapse - Maximum Output: Division:  divides the intended target continuously as long as the technique is active.

Curse Technique Reversal: Addition: can gradually add the amount of curse energy that is targeted.  It can also target physical objects and concepts that the user is aware of.

Curse Technique Reversal - Maximum Output: Multiplication: can double the intended target continuously as long as the technique is active. Negative Dragon:  summons tiny dragon like creatures that can use the Subtraction technique themselves but to a lesser degree.  Once five Negative Dragons form they can merge together to form a bigger form.  This larger form has the same abilities but they are stronger.  Similar to the first form the rest of the forms can merge to make bigger and stronger forms until they reach its final form: Divine Negative Dragon.  The Divine Negative Dragon can use the Division technique as well as the Subtraction.

Positive Dragon:  Similar to the Negative Dragon but formed from positive energy instead of curse energy.

Dragon Forms: Hatchling Youngling Adult Ancient Divine
