Guide
A relatively challenging Town Mission, the player starts out on the bridge in Soleanna Forest. Scattered around the forest are many blue portals (some of which are marked by wooden crates with numbers on them). The player is required to travel between these portals in order to reach the goal ring hidden somewhere in the forest. Only one particular combination of portals leads to the goal.
