Jobstones

[TheMightyMollusk]

However SCH retains actual pet control being somewhat core to their job design which despite the ground up rework is still very much part of ACN’s lore

SMN meanwhile could delete carbuncle tomorrow and nothing would change

SCH thematically flows better from ACN than SMN does

Scholar's fairy is an entirely separate entity that comes with their job stone. Carbuncles and egis are both created from the caster's aether. (Which also explains, in lore terms, why we can glamour the egis back into carbuncles, but not the fairies.)

ACN also doesn't actually control the carbuncle in any meaningful way anymore either.
