Darksiders II Deathinitive Edition

First off, this is just a tad harder than Apoclyptic difficulty, no perma-death or dumb gimmicks here!

Now, there are two cheeky exploits that will make this achievement much easier. One lets you buy all the stock of any store even with 0 Gilt (This world's currency) and the other exploit let's you over-upgrade possessed weapons (this can backfire if not careful). I'll go into more detail on how to do both below.

How to buy anything from any shop regardless of Gilt

Go to any store and then go to the Sell tab
Press and with a very very slight delay between each press and it should have you switched over to the Buy tab but with a pop up saying "are you sure you want to sell this item?"
Select Yes and it will buy the item, if you do have Gilt on your character it will use it up, but again you can do this at 0 Gilt and you're able to sell the items back to make profit which you can use to buy abilities from Thane and Draven (You can't use this exploit on them as there is no Sell tab).

The advantages of this exploit are buying the best gear for your level and that you can overstock yourself on health potions! Usually you can only have a max of 5 health potions but I finished the game with 32 left to use.

*Edit* Be cautious when using this glitch with Vulgrim's store!
As mentioned by ViníciusLCH in the comments, if you do this glitch at Vulgrim's Store and use your Boat Coins currency it will actually drop the currency amount into the negative and won't go back to normal until you collect enough Boat Coins to bring it back to zero. This also carries over to New Game+ also.

Here's a video showing how to pull this off incase my instruction aren't clear (Credit to zombiekillerhere) :


How to over-upgrade your possessed weapons

This one is pretty simple, but can backfire if you get too greedy.

Upgrade a possessed weapon until you can't anymore. (The upgrade option text is now red.)
Drop the possessed weapon. (You can't drop it if it's equipped.)
Pick the weapon back up and it will allow you to continue upgrading it.

Use this in tandem with the store exploit above to obtain plenty of items to upgrade you're possessed weapons.

The problem with this is if you keep upgrading you'll eventually see an upgrade option of INVALID ID which if selected will delete one of the possessed weapons effects, so don't get too greedy and you'll be fine.

If you want to know the best effects to use on your possessed weapons my recommendations are:
Critical Chance
Critical Damage
Execution Chance
Health on Kill/Health Regen/Health on Execute


Extra Tips

I chose the Necromancer upgrade tree for this difficulty as the summoned ghouls can help with taking aggro off you in a pinch, I'd recommend spending skill point in all the ghoul skills and maxing each one out before selecting anything else.
If you do choose Necromancer then equip gear that provides Arcane stats as the higher your Arcane the more potent your Necromancer abilites are.
If instead you chose the Harbinger upgrade tree then focus on getting gear with Strength instead of Arcane.
