You can farm this very quickly at "Martin Feuille's Farmstead" (fast travel point) in the north of Novigrad. There is a group of over ten cows in this area. Kill them all, then meditate for a day to make them respawn. Kill more cows until you get the "Moo-rderer" achievement. If there are no cows when you arrive, meditate and they will eventually spawn.Easy "Rad Steez, Bro!" achievement
There are many mountains in Skellige where you can slide downhill uninterrupted for at least 10 seconds. A really good area to do this is at the "Distillery" fast travel point in the east of Skellige's main island. Save the game when you reach the fast travel point, then slide down the hill to get the achievement. If anything goes wrong, simply reload the saved game and try again.Easy "Return To Sender" achievement
First, buy the "Arrow Deflection" skill (Level 3/3) in the combat skill tree. Then, find some archers and parry their arrows just a moment before they hit you. A great area to do this is at the eastern bridge of Oxenfurt. There is a fast travel point and some archers on the bridge. After killing them you can meditate for an hour and they should respawn. Repeat this until you get the "Return To Sender" achievement.You are also allowed to weaken them with your sword. Only the final hit has to be from a deflected arrow. Easy "Shopaholic" achievement
You only need approximately 1,000 gold to purchase all three items on the block at the Borsodis' Auction House and get the "Shopaholic" achievement. Keep selecting one dialog.Easy "When It's Many Against One..." achievement
The fight against Iris' Nightmares takes place at the end of the "Scenes From A Marriage" main quest after recreating the memory in the dining room. Create a manual save game before the fight. It is also highly recommended to play on the lowest difficulty. When the fight begins, one nightmare will be fighting you while five are standing still. Go around the room and hit each nightmare with one light attack to provoke them. It is recommended to do this from a far distance with a crossbow. If you hit them more than once they might die -- so be careful. If done correctly, there will be a total of six nightmares fighting you at the same time. If you killed one already, you must reload the last checkpoint. The quickest way to take them out is by using the Whirl skill, but you can kill them with any attack.Steam achievements
