From Tatroi, walk all the way back to Tropp, sail to Eckdart, and walk again all the way to Van y Ille. You don’t have to enter the city; just follow the road to reach the Checkpoint Bridge. Talk to the guards to pass, then enter the Cave.
From the entrance, take the path to the right to get a Combo Link from the chest. Return to the main path and follow it to grab the Green Beryl along the way and continue until you exit the cave. Once you’re in the world map, follow the road. There is an off-road town in the mountains. You can check it out if you want.
This quiet mountain town doesn’t have much to offer but it can be a good stopover on the way to Silvalant. There is an inn and some shops in case you need to rest and resupply. The weapon shop sells cheap Equipment so just ignore it.
Once you’re done exploring Druss, you can return to the main road and follow it until you reach the kingdom of Silvalant.
