Some job changes are currently different than the farther progressed servers due to towns like Hugel not being available yet.

All first class job changes are the same for both Renewal and Classic RO. Archer, Mage, Thief, Swordsman, Acolyte, and Merchant.

Priest, Assassin, and Knight are normal as per Renewal and Classic RO.

Wizard testing is correct.

Hunter can be done using the iROWiki Classic Quest. The combat part of this quest is currently disabled for some reason.

Blacksmith can be mostly done using the iROWiki Classic Quest with the exception of the Bismarc NPC being located in the weapon shop in south Alberta.

Monk job change follows the Renewal job change quest.

Sage job change mostly appears to follows the Renewal job change quest but some questions may have been swapped around.
