Your next task will be to track down the Grand Regent. He is on his way to Watchwaeld Temple, so you will have to follow him through Crow’s Pass.
Spiders make up a good bulk of enemies here. They can poison you, so equip to protect against poison if you have something fitting.
When you see the groups of small spiders, do what you did in the previous quests and use your concentrated area attacks to take them out.
Once you get to the end of the path, speak to the person that has been traveling with the Grand Regent. Doing so will initiate the next part of the quest. Seems the doors have been sealed behind the Regent after he went into the temple. Word has it that there is a mysterious illness going around as well…
