The Spellbook contains spells which perform various functions and which require runes to be cast, using the magic skill. There is only one Spellbook in RuneScape Classic.
There are six specific types of spells, each of which has a different function and rune requirements.
| Spell Type
|| Runes Required
| Summoning Spells
|| Summoning spells to have a follower creature or aid in combat
|| life-runes, elemental-runes, and sometimes essence of the summoned (for example bones)
