On the steps of the Academy of Arcane Science, you will find Knight Gold
In North Freeport lies your next Archetype step. On the steps of the Academy of Arcane Science, you will find Arcanist Sonius, who gives the Knight Gold quest for you to determine your next class choice, you need to become a Summoner to progress to Necromancer, so be sure not to choose Wizard or Enchanter!
Sonius will have you run 3 errands, one that depicts the way of a Wizard, one of an Enchanter, and lastly Summoner, where you will take the floating elevator to the basement of the Academy and enter a room where you summon your first creature.
When you enter the chamber you will want to first read from the Spell Book sitting on a podium, then collect the ingredients it asks for from the 3 locations within the room, and finally walk over to the small patch of carpet in the corner.
You will automatically place the items on the rug and a few seconds later a stone beast will appear, which you have to slay!
You must do this alone, so you may want to wait until level 9 to complete this part. After you slay the creature, talk to Arcanist Sonius to complete the quest.
