Dungeons & Dragons: Daggerdale

100k gold is not much of an effort, even without duping items, especially endgame. If you want this the proper way, just save your gold, sell what you don't need (without converting it to gold from inventory), and refrain from buying items you don't need. I had no trouble playing through all chapters without ever buying anything other than the odd healing potion here and there. By level 9 and before finishing the endgame, I had roughly 75k gold.

Note that this has to be on one character and at once. You need to have 100k+ in gold on your person and the achievement will pop instantly.

Getting the last bit can be a bit boring, but there are several ways. Some prefer to grind the endgame sequence, but I found the droprate to time spent a bit on the slow side. Try saving your game after you have completed it, then load up a new chapter. Pick Mouth of the Void as you start in The Depths after finishing the story.

From here, turn around and open the chest to your left, then follow the map around in circular path clockwise back to the portal where you can engage the end sequence again. Along the way are several chests with loot, and several Ghouls with a good droprate. Once you hit the last Merchant before the portal, sell your stuff, save, and load up the same chapter again. You'll be teleported back to the beginning and can do the round as many times as you need. Each round will net you 3-5k gold and take about 10 minutes.

More tips:
- Higher level enemies drop better loot and more coin, and barrels drop more coin and better loot in chapter 4 than chapter 3.

- If you have some nice purple items you wish to keep, check their value. They are often worth 1-2k. If you lack only 10k gold, check to see if you can sell all your purple gear to reach 100k, then just load your game after the achievement pops.

- Charisma will affect merchants prices. The more you have, the more gold you get when selling items.

- With a good regeneration ring/amulet, all those healing potions can be sold.

This Achievement is very hard to do if you do this without cheating. Thankfully, you can.
The easiest way to do this is to have a friend with the game (online only offline co-op does not work) and play for a bit until you get an item or 2 that sells for about 1000 or more gold (any less and it takes a bit to long).
Now once you have that item save the game in the start menu. That being said you are going to duplicate this item and the way to do that is the person who is not the host of the game is the one who has to have the item in there inventory at the point of the save, drop the item ( inventory screen press x) after the save icon goes away, leave the game (without saving after dropping the item) come back and there you have it the item is now on the floor and in your inventory, pick up the item so now you have 2 of them, save then drop afterward.(Edit: after you drop the item let the host pick it up. It has come to my attention that if left to long on the floor it disappears)
Rinse
Wash
Repeat
Until you have basically a full inventory's worth.
Now Let your friend pick up the full inventory's worth and you leave with out saving, they sell you come back (might have to do this a few times).
After they get the achievement come back once more and give them all of the items then they and everyone leave the game so now you have your items still and he has his. then you host a game and he joins and repeat the above pattern until you receive the desired results.

you can even give it to a mule character later so you can always have a constant amount of those weapons that you can sell so you can either help out another friend in need to fund your other characters in the hopes of getting the

This may sound like bad advice, but the best way to get this achievement with little effort is to simply just play the game and go for the other achievements. When your characters are all level 10, you will have more than enough gold and gear to unlock this achievement.

Here's what I did:

1) Never spend gold. The merchant weapons are only ever *barely* better than drops you get in the game (like they'll do 8-12 damage instead of the 7-11 one you found in a chest). If you never waste your money and open all chests you run past and pick up all loot, your character should have about 50k when you hit level 10.
2) Equip everything you find that gives you better stats. Sell everything else. Keep only your equipped gear and healing potions.
3) Complete every character to level 10.
4) Spend all gold from 3 of your characters on expensive gear.
5) Create a "mule" characer on a second controller. Use it to transfer the expensive gear to the character where you're saving up gold.
6) Sell the expensive gear and you should be at 100k. If you're stuck at 80-90k after doing this, just go to the final boss fight and spend 15 minutes killing mobs and picking up the plentiful loot. You pretty much always warp out of that place with a sack full of expensive gear.

No offense to the other solution posters, but the only time you need to pull off tricks and cheats is if you *ONLY* want this achievement and have absolutely no plans to get the full 200. If you're going for the 200, don't waste your time pulling off fancy tricks. You will get this naturally by just playing.

Actually, I finished this achievement in "offline co-op"!!!

B4 to get this achievement, I already have the 4 characters Lv10. Each of them do have some several thousands gold in there hands. I used one of these characters (said "Character A") who get the more gold in hand for the achievement.

First, use Character B as player 1 to host a game, and for player 2, login in another gamertag and create a new character. Character B goes to the shop and spend all his mony to buy items, and then drop all them down on the ground for player 2 to pick up.

The fact is that after saving and leave the game, the player 2 "game save" is under the other gamertag and separate with the one u previous used to play for the game.
I then exit the game, use the other gamertag to login to Xbox Live (u need to do this~the save cannot be moved/copied under the wrong gamertag), backup the player 2 game save in USB device.

Use the Original gamertag to login again-->get into the game-->choose local multiplay-->player 2 transfer items to Character A-->exit the game-->player 2 login to live-->copy the save in USB to overwrite that one in HDD~~~that means player 2's character still get those items from Character B!!!

Repeat this process, Character A easy to get 100,000 gold !!!
