Magic costs sparks to cast and require the Slaver to have skill levels in Magic to cast. Some effects last for a day and can't be recast during the day; this applies to all the spells but Delikacia, Cruciato and Adverto Servili. (Adverto Servili is permanent and can never be recast on the same slave, while Delikacia and Cruciato can be cast without a set limit per day.)
V2.2.3: Additionally, Delikacia and Cruciato have some effects that only apply to the first cast of the day, such as improving your magic level. Aside from this restriction, casting any spell increases your magic level but only on a successful cast. Exception: Successful Auspex can only take you to up to Apprentice (D rank).
This means any mundane character must buy wizard robes in order to train magic skill. (And you should, because not having magic skill in the Eternal Rome is almost like not knowing how to use a debit card: Embarrassing.)
It takes 320 Successful casts to max out your magic skill, though you can also raise your magic skill by teaching both alchemy and magic.
Description: Allows you to read a slave's aura
Available even to Mundanes; but casting without wizard robes will cause the spell to fail. Casting it while wearing robes can raise your base skill level to Apprentice mage but not above.
It takes 10/19 (2.2.3/Original) casts to level the skill from Mundane to Apprentice.
Made obsolete by acquiring the Raven Crown from Master Valios.
Description: Inflicts pain on the slave according to their guilt.
Available to A+ mages and up (B+ with robe).
Jack Original: Casting it can improve your magic level to "Mage" but not above
2.2.3: Unless the slave resists, it will always increase magic level
2.2.3: Increases Mood and Devotion according to slaver's magic level. Also increases Awareness once per day. Slightly lowers intelligence.
Available to A+ (B+ with robe) Mages and up.
Jack Original: Casting it can raise your level to "Mage", but seemingly not above. It's approximately 21 casts from apprentice to Journeyman, and about 140 casts from journeyman to Mage.
Description: If target has no merit or guilt, increases degree of merit or guilt at the next receiving.
2.2.3: available at C- magic skill, or D- with wizard robe; contributes progress to magic skill up to S+ Only available when target has no merit or guilt. Drains awareness proportional to intellect, but increases taming.
Jack Original: Available to Apprentice mages and above; casting it can increase your level to "Mage" but not above.
Description: Strengthens the caster's aura depending on the magical powers of the caster.
2.2.3: Available at D- magic skill, or F- with wizard robe; contributes progress to magic skill up to S+. Can not fail casting, so an easy way to train magic skill.
Jack Original: Available to Apprentice mages and above; casting it apparently cannot increase your magic level. (?)
Description: Causes the slave to be deeply afraid of the slaver.
V 2.2.3: Available to B+ mages (C+ with robes) Only raises mage level (when successfully cast) up to A+ rank. Failing to cast this spell is a great way to make your slave prideful, and not very scared of you at all.
Jack Original: Available to Apprentice mages and above; casting it can increase your magic level to Archmage, and it does so whether the fear succeeds or not. It takes approximately 7 unsuccessful casts to level the skill from apprentice to Journeyman, about 49 successful ones to go from Journeyman to Mage, about 100 casts to go from Mage to Magister, and about 163 casts to go from Magister to Archmage.
Description: Causes the slave to follow all orders of the slaver if slaver's magic force is as strong as or stronger than the slave's nature.
2.2.3: Available only to A+ mages (or B+ with robe) May cause sever depression in your slave, unless they like helplessness.
Jack Original: Available to Apprentice mages and above; casting it can increase your magic level to Archmage, and it does so whether the domination succeeds or not. It's approximately 10 unsuccessful casts from Apprentice to Journeyman, 25 from Journeyman to mage, 51 from mage to Magister, and 82 from Magister to Archmage.
Description: Magically puts your brand on the slave, making it difficult for them to run away. This method of putting your brand, just like any other method, permits you to sell the slave to persons other than Farid.
2.2.3: Also removes illness and parasites, and gives a one-time boost to energy.
Available to S+ rank only and can only ever be cast on a particular slave once.
