Epic Spell: Spells that are different from common spells.
Epic spells are usually custom-made.
Epic spells do not take up normal spell slots, but instead are gained and used under a completely separate progression.
Epic Spell Slots: A character must have an available
epic spell slot to prepare or cast an epic spell, just as he or she needs a normal spell slot for a nonepic spell. A character doesn't gain
epic spell slots by
virtue of his or her level and class, however. A character gets one
epic spell slot for every 10 ranks he or she has in the relevant
Knowledge skill.
