|Prerequisite||Complete Alduin's Wall.|
Recruit three followers into The Blades.
Kill a Dragon at Esbern's command with the new recruits.
After recruiting three followers into the Blades, Delphine will tell the Dragonborn to talk to Esbern about doing some Dragon Hunting. If he knows about a new location with a dragon present, head over to said location and kill the Dragon with the new recruits.
Return to Sky Haven Temple and Esbern will ask the Dragonborn to provide him with Dragon Scales and Dragon Bones for his research (one of each). Upon obtaining the scales and bones, Esbern will reward the Dragonborn with Esbern's Potion. Drinking it will grant the Dragon Infusion ability, a permanent 25% resistance to the melee attacks of dragons.
- Currently, Esbern's Potion does not add the intended effect. PC users can add the perk manually using the console by typing "player.addspell f5ffa". This bug has been fixed with Title Update 1.9.
- "Bring a Dragon Scale and a Dragon Bone to Esbern" may not disappear from the Miscellaneous Quest list when you have delivered them. This bug has been fixed with Title Update 1.9.
- It seems that Esbern will occasionally direct you towards a dragon to kill, even if you have already killed it before obtaining the quest. The quest is unable to be completed if this occurs, seeing as the dragon is already dead.
- You can complete this quest without actually having it. Recruiting 3 followers is, hence, unnecessary. Complete Alduin's wall, kill the dragon. A new miscellaneous objective will tell you to return to Esbern. However, he might not actually have any dialogue options about this objective. This could be due to Paarthurnax still being alive.
