I would first try using the feature "questfinder" to make sure you didn't miss any quests by mistake. Also, make sure you have all of the fire spells that are currently available to you! Some spots that may be frequently missed by fellow wizards are:
- SabrinaGreenstar at the Wizard City Fairgrounds
- Mortis the Death School tree in Nightside
- MildredFarseer in Colossus Boulevard (To get to Mildred, go to the first "clearing" in Colossus Boulevard and find the NPC Mindy Pixiecrown. If you stand behind her and face forwards, you should see a path leading down to a single house with its lights on.)
-Croaky in Digmoore Station (Go to Digmoore Station and find the NPC Mayor Pimsbury. Behind him, there should be some stairs going down, which will lead to the Air Dales Hideaway.)
Good luck, and I hope I was able to help to some degree!
You might be a missing spell. Here's a checklist for the Fire Spells from secret trainers - (Make sure you have all these~)
- Fire Shield (Sabrina Greenstar) - Fuel (Erik Wyldrune in Grizzleheim) - Quench (Given by Mildred Farseer in Colossus Blvd) - Take Power (Given by Croaky in Digmoore Station) - Tranquilize (Given by Mortis)
Sorry if I missed any cx But yeh, make sure you have all of those. c:
