The Elder Scrolls V: Skyrim Special Edition

Let me start by saying get the Cursed Ring of Hircine which is obtained during the quest "Ill Met by Moonlight", from the werewolf Sinding, who is imprisoned in Falkreath. For this quest you have to agree to kill the hunters and not who Hircine sent you for.
Hircine's Ring is a powerful Daedric artifact that grants the wearer unlimited werewolf transformations instead of once a day, though only if they already possess lycanthropy.

To be able to become a werewolf you have to progress through the Companions questline in Whiterun, it will be part of the blood ritual that occurs during the Companions quest, The Silver Hand.

After you have this you can activate the werewolf form by then choose magic , go to powers and then on Ring of Hircine and while in game to activate. Will have to mention also that you have to equip the power again after each transformation so will make it easier to have it as favorite.

Now while in werewolf form when you use you will see the werewolf perk tree. The achievement is basically to get all 11 perks here. You get perks by feeding on corpses hearts. To feed you need to get close to a corpse, you do not have to have been the one to kill them, and a prompt to press will appear to feed - this will extend your Bloodlust and allow you to stay a werewolf 30 seconds longer.

Each new perk requires a few more feedings than the last. A total of 164 feeds need to be fed upon to complete the entire tree.Worth to mention also that you can get Savage Feeding in the Perk tree to be able to feed off most dead creatures.

Perks 1 2 3 4 5 6 7 8 9 10 11
Feedings 5 6 9 11 13 15 17 19 21 23 25

Total = 164 Feeds

Have in mind also that you can go in a dungeon kill all with your character and after transform to werewolf and eat their hearts, for me at least i found it to be more helpful as you cannot read books or pick locks or loot corpses in the werewolf form.

Also a note the achievement for on the Xbox One did not pop for me when i actually put the last perk. I waited a minute or 2 and then I just when and checked the achievement list and it was already unlocked just it did not pop , had me a little worried there.



Good luck and enjoy Skyrim on the One!

EDIT :PraXis91x has gave a nice tip also that you can transform back to normal and cast Soul Trap on everyone you fed and you get a freebie, so it only takes 82 feedings .

This is a 15-30min achievement grab allowing you to basically skip needing to be a Werewolf, especially if you're putting off Dawnguard. Just try to RT swipe at the ground in front of people or you'll trigger the maul animation which is sooooo looooong.

Requirements:
- Be a Werewolf
- Sell the Ring of Hircine or ignore it altogether

Step 1: Join the Civil War and get a Fort capture quest
Step 2: Join up with the men attacking the fort and SAVE.
Step 3: Go Beast Mode, stand in a doorway between the fort courtyard and Skyrim, then start killing FRIENDLIES. Ignore enemies, friendly AI will infinitely spawn and also attack enemy AI. Feed after every kill
Step 4: Grind out all 11 points. Kill, feed, level, rinse and repeat. Listen to that sweet rare achievement jingle.

No need to worry about the friendly AI killing all the enemy AI; once the quest percentage falls to 0, the enemy will flee and the quest will complete. Ownership of the Fort transfers to the friendly AI you're killing and they continue to infinitely spawn.

Also no need to worry about roaming for kills, there should be 4-6 enemies around you at all times. If there are none, you may have to aggro some bowmen into drawing swords by walking near them.

So long as you're level 20ish, you'll regen health feeding faster than they can damage you. If you're under 20, I recommend kiting swordsman out of archer lines of sight and forcing them into close range combat.

Once you get the achievement, simply reload your save from Step 2. Enjoy!

This is not my video, if you'd like to credit the OP please like their YouTube video.

This only took me 30-40 minutes, and was the last achievement I did in the game. Recommend making a save before going for this as it's easier if you kill named NPCs as well as guards etc.
