The Spell Prowess (or SP) indicates, how well a hero can cast a certain Spell. If the hero does not have any knowledge of a spell, he also does not have a Spell Prowess for it. Such spells can be obtained from Trainers in exchange for Experience Points and Ducats.
A spell prowess of 0 means, that the hero has learned the corresponding spell and that he can raise his spell prowess by spending Experience Points on it.
The maximum spell prowess to which a hero can raise a certain spell, is limited:
- Spells: base value + Level + 3
- No spell may be raised higher than the highest Attribute involved +3.
The base value is the value which is displayed in Expert Mode of the character creation screen, after resetting the distribution of all the Experience Points.
