Hello, I am Jason Hexeys, a level 19 Ice Wizard. I have gotten the quest to defeat Grubb in Sunken City, and get the item of proof. Problem is, There is no way in the Spiral I can do this alone. Can any advanced Wizards help me with this? :)
As timing of post versus appearance on boards is not immediate, you may have better luck asking in-game either in Commons or around Sunken City and don't forget about realm switching; shouldn't be hard to find wizard(s) willing to help.
If you go into "Crowded" realms, you'll eventually find others waiting to go. Also, you can ask for help on the Wizard101 Central forum, where posts appear in real time.
