Job Point Suggestion

[Protey]

You can't accession anything that SCH main can't cast. The highest Accession'able cure would be Cure IV.

SCH main in and of itself can't cast enspells, but RDM/SCH can accession those.

[Martel]

SCH main in and of itself can't cast enspells, but RDM/SCH can accession those.

Way to take things extremely literally.

SCH/RDM can cast enspells. A SCH/RDM, is still on SCH main.

There are also a few exceptions. A major example would be haste. SCH/RDM can cast haste, but haste does not work with accession.

But the general rule is, if a SCH/xxx can cast it, it can probably be accessioned.

To counter your example, a RDM/SCH can cast enspell IIs, but they won't accession. Same for PLD/SCH and Enlight, or Reprisal.
