So the Eldritch Scion Magus Archtype says it replaces Spells class feature but not the Spellbook class feature, however later on it goes to say that the amount of spells known by an Eldritch Scion and the ability to replace them is the same as a bard which does not make sense if the Eldritch Scion has a spellbook. My friends and I are wondering if the Eldritch Scion has a spellbook or not, and if so, how does replacing spells work with a spellbook? Also if they do have a spellbook, does that mean that this is one of the few, if not only spontaneous caster that can know every spell on its list just because of the spellbook?
A clarification on this would be appreciated. Thanks in advance.
