Intelligence

Intelligence is one of the six character abilities. It is of prime importance to arcane casters as it determines which levels of spells can be cast by mages, bards, and specialist mages, the chance a spell can be written down in the spellbook from reading a scroll and determines how many different spells of one level may be memorised in the personal spellbook.

For sorcerers, the amount of spell for each level is determined solely by the level of the mage - as they can naturally cast 9th level spells and do not scribe scrolls, the only benefit they gain from a high intelligence score is a lore bonus.

For non-caster classes, intelligence and wisdom only adds a bonus to lore bonus, so it's wiser to spend points on the other character abilities when creating a character. A minimum intelligence of 9 is needed to use wands and scrolls.
