Shadows of the Heart
The art of inscribing a spell into a gems was lost when the bombs fell. However, these gems, called Spell Matrixes, can be found in robots and in factories, waiting to be used. Most often a ‘Come to Life’ spell is found in a spell matrix so a robot can be brought to life. However, sometimes spell matrixes are found containing another spell. Some contain multiple spells, though those are rare.
To identify a spell matrix, a successful Science check must be made. This check has a difficulty of -10 for a Novice Spell, -20 for an Advanced Spell, and -30 for an Expert Spell.
An Earth Pony can install a spell matrix into a spritebot, should they have the perk Robotic’s Expert (Rank 2). This will allow a Sprite Bot to energize the Spell Matrix, firing the spell (or the spell of its choice) once per round. Should it be installed with a spell matrix with multiple spells, each spell may be fired for 45 AP. A Sprite Bot is considered to have its owner’s amount of AP, and fires the spells with a Potency and Versatility of 1.
A Unicorn can energize a spell matrix (assuming they are holding it by hoof, mouth, or with a spell) for twice the strain of the spell inscribed inside the matrix. It costs the same amount of AP as any other spell the unicorn can cast, and such spells can be stored inside a Spell Closet. The spell is cast with a Potency and Versatility of 1.
A Unicorn with the Matrix Caster perk may energize a spell matrix (assuming they are holding it by hoof, mouth, or with a spell) for its normal strain cost. That spell is cast with the Unicorns full Potency and Versatility.
Intact Spell Matrixes in the Northern Empire vary in cost depending on the spell. Generally, they sell for less than a hundred to several thousand caps, depending on the rarity of spell and the difficulty it would be to learn it normally.
