Why no official documentation about how to unlock Job?

SMN's cross classes are THM/ARC not THM/CNJ btw*

Edit: turns out the information I was looking at was wrong, SMN *IS* THM/CNJ, my mistake

Here you can see where they listed Archer as a cross class for SMN, which is incorrect, Archer's only a cross class for BLM

Edit Edit: apparently Archer IS a cross class since the last patch... or might not... so SMN is either ACN + THM/ARC or ACN + THM/CNJ

[Ruanark]

For the minimum lvl you need to lvl cross classes in order to obtain all available cross class skills, here's a list:

THM: 26 (SMN, SCH, WHM)
ACN: 34 (BLM, SCH, WHM)
CNJ: 34 (SCH, PLD, SMN*)
GLA: 34 (WAR)
MRD: 26 (PLD, DRG, MNK)
LNC: 34 (MNK, BRD)
PUG: 42 (WAR, DRG, BRD)
ARC: 34 (BLM, ACN*)

So, a BLM needs lv34 ACN and 34 ARC to have all cross class skills,
WHM needs 26 THM, 34 ACN
SMN needs 34 CNJ(or 34 ARC*), 26 THM
SCH needs 34 CNJ, 26 THM
PLD needs 34 CNJ, 26 MRD
WAR needs 34 GLA, 42 PUG
DRG needs 26 MRD, 42 PUG
MNK needs 34 LNC, 26 MRD
BRD needs 34 LNC, 42 PUG

*Appears some sites SMN as being THM/CNJ and others list it as being THM/ARC, we'll find out soon which is correct

SMN's cross classes are THM/ARC not THM/CNJ btw

every job cross class with 3 classes

the main lv30 class

the sub-class lv15

and 1 additional

so SMN will cross class ARC , THM & CNJ

ACN does not count as a "cross class" for SMN because ACN is SMN's main class and cross class refers to the sub classes of that job
