The Sad Tale of the Grossbart Brothers
Prerequisite: None | Suggested Level: 26
At the town of Blandare is a bounty hunter named Djenge Frett (what a reference, eh?) who wants your help tracking down a group of criminal brothers. Agree to help, then head to the southeastern edge of the isle.
You have a wide search area here, but you want to look for a grotto (it has its own fast travel marker) along the coast. This is the brothers' lair. Head inside to meet up with Djenge, then follow him through the cave. You'll soon come across the brothers. Quickly take them out, as they can cut Djenge down pretty quickly. The quest ends after the fight.
Freya Be Praised!
Prerequisite: None | Suggested Level: 4
Just southeast of Blandare is an abandoned cart, marked as Hidden Treasure. Loot the corpse near the cart for a letter and a key, then read the letter to learn of some treasure in the water nearby. Dive in and use your Witcher Senses to find it, and unlock it with the key you just looted.
Prerequisite: None | Suggested Level: 24
You can find this quest at Gedynieth Grove, northeast of Blandare. A druid by the big tree will ask you to help a fellow druid break his silence. Head to the druid in question to get started.
First, use Aard on the nearby pots and pans when he falls asleep. He'll then move to a different spot. Use Aard on the hornet's nest near this new spot to make him move again. Lastly, he'll light a fire. Extinguish it, and he'll finally speak out of anger - toward you. Return to the druid who gave you the task to complete the quest.
