How to unlock the Munchkin achievement in THE WITCHER 3: WILD HUNT - Definitive Guide
If you save all your contracts and are playing on Death March! (which gives less XP), you might encounter a situation where you haven't attained level 35 after finishing the main quests. In this case, the best thing to do is to farm a specific Cyclops. He is on the far east side of Ard Skellig, next to a place of power and the mastercrafted griffon gear.
He gives 51xp per kill on Death March (some report only 33) and 81xp per kill on Easy (according to comments), and you can make him respawn by meditating for an hour. If you're just short (as I was), this can get you there. It only took me about 20 minutes to finish up. It would have taken far longer to pick around trying to do side quests for minimal or no gain (and I'm not sure it would have been possible with them).
Here's a video. It's not mine, but it's where I learned this.
After you have finished the game you can then kill this one cyclops to for quick exp. See video får further details.
In order to reach character development level 35, you will need to amass a total of 54,000XP. Geralt will earn experience by slaying opponents, completing quests, accomplishing special tasks during quests, or by making certain conversational choices. Additionally, visiting Points on Interests (indicated by a question mark on the world map) and resolving the tasks that await there earn some experience. If you want to level up quickly during your playthrough, then be ready to jump at every chance you can take, regardless of the task's level of importance.
In regards to combat XP, experience gained from fighting changes depending on the level of the enemy relative to Geralt's. If the opponent's level is white, you gain reduced XP. If their level is green (meaning they're close to your level), you gain a standard amount of XP. If you're facing a red-leveled or "skull-leveled" opponent, chances are you might die, but defeating them yields increased amounts of XP.
Take into account that from levels 1-10, it takes 1000XP to level up each time; from levels 11-20, it takes 1500XP; and from levels 21-70, the highest level in the game, it takes 2000XP. The difficulty you are playing on will not effect the amount of XP you gain, so just complete any and all tasks that come your way and this achievement should be yours at the very end of your playthrough.
NOTE: After completing nearly all of the content in your playthrough, you may still need to gain one or two levels to reach Level 35. If this is the case for you, you can farm XP from a Level 30 Cyclops on the east coast of Ard Skellig (near the Place of Power and Mastercrafted Griffin Gear Diagrams). The Cyclops nets 51XP per kill and will constantly respawn after meditating for two hours.
Level 35 will require 54,000XP in total. You gain experience from quests, special conversation choices, and defeating enemies. You gain little experience by defeating enemies or by conversation choices in comparison by quests, so your best bet is doing quests.
If you go for all of the other trophies, complete all 26 witcher contracts and participate in side quests and map exploration, you should reach level 35 by the time you finish the final story mission. The last story missions also give a lot of XP and you will be able to get several level-ups within just a few hours (1000XP+ per mission). Liberating abandoned sites in the open world also grants decent XP bonuses. Just do everything available to you and you will get to level 35 naturally.
This quest will become available after completing the quest "Tower from Nowhere".
What to do? Here's what: try to complete only those quests whose level you have already outgrown. Try to follow them in such a way as not to complete quests that are still higher than you, albeit by a couple of levels. After all, then you will “overtake” those quests that have already outgrown and will not receive experience for them. Example:
Let's say you are level 10 Geralt. You have 5 quests in your journal - with recommended levels 5, 7, 9, 11 and 13. If you begin to complete quests with a higher level, then by receiving exp for them you will increase your level and the 5th level quest will become gray for you "(they will give you 5 exp for it). And if you complete lower-level quests first, then the exp for them will be given in full, because... at that time you will not yet outgrow them by 6 levels.
By playing with this tactic, you will be able to reach the required level 35 by the end of the game.
