Torchlight 2 Walkthrough Part 3: Regroup At The Enclave & Trail Of The Grand Regent
After beating Grell, you will have to regroup with the others at the Enclave. This quest is about as simple as it sounds. Simply head through the portal at the end of the dungeon and speak with the Guardian in the Enclave to receive this quest. Walk through the portal and speak with the woman right next to the gate. You will get your reward and complete the quest.
The next mission is a little more exciting. The Grand Regent is on his way to the Watchwaeld Temple, and you need to catch up to him before he reaches it. In order to do this, you will have to navigate the Crow's Pass. Along the way, you will encounter Spiders for the first time. If you have any items with Poison resistance, now would be a good time to equip them. You will likely stumble upon a named enemy or two along the way. Take them out for special loot. If you're having trouble, remember that you can scan the bottom of their lifebars for a list of their abilities and characteristics. Equip items that will help you out in the battle.
As you advance through the snowdrifts, you will encounter spider holes that spawn the little guys in hoards. Use area of effect attacks to take out the tiny spiders, and powerful focused attacks to take out the bigger ones. You may also encounter a Monstrous Shrine. As you approach, a random assortment of creatures will spawn from it and attack you. This is a good way to earn experience points, but be careful, as you can never be sure what will spawn from one of these things.
When you reach the end of the path, you will find that the Regent has already moved on. You will now have to take on the Ember Keys quest to further the story.
