If you are having issues getting a skill quest, it could be due to having another 'Advanced' skill quest in progress. Players can only have one 'Advanced' skill quest at a time. This only counts towards skill quests you receive when talking to a NPC. Certain quests include:
- Acquire the Ice Spear skill book
- Learn Arrow Revolver
- Learn Fireball
- Rank up your Shock skill to F.
- Creating Harmonies with Empty Bottles
- Earn Thunder Skillbook.
