How to Complete Ogden’s Theory Side Quest
After completing the first quest from Ogden, you get to unlock his second quest. Speak to him at the camp in the western section of Sheparden. Your goal here is to seek out the Exotic Seregios and defeat it for Ogden. Before you venture forward, you need to own two particular monsties in your party:
- Any flying monstie
- Arzuros

The quest marker will lead you to Canalta Timberland’s Blessing Hill. Once you reach the Blackwoods Catavan Stand, follow the river north until you spot an opening on your right. Go up the hill and continue east until you find a path going upwards to the west. Continue up that path, then fly across the gap. Continue to go uphill to find the quest marker ahead.
After the cutscene ends, continue to travel south to find another quest marker near a tree. Once that cutscene ends, your next task is to find a way to lure the Exotic Seregios. This requires you to ride an Arzuros and interact with the tree quest marker again. Defeat the Exotic Seregeios to complete the quest.
