The feature is already present as all Epic and Legendary items have socket removal prices but the Devs did not implement it in to the game probably for balance reasons. All i did was to change a code line and voila less restrictions more power!

Requirements for the actual files (also mentioned on the download page):

Installation:
1.Can be installed at any time no need to start a new game and platform shouldnt be a problem.
2.Before doing anything make a backup of the original Game.dll usually located in:
D:\Games\Titan Quest Anniversary Edition Atlantis or Eternal Embers.
3.Simply replace the original Game.dll with this one.
4.Thats it Epic and Legendary items can now be enchanted.
5.Choose carefully as the disenchant price for this items is pretty high.
6.To revert the process bring back the original Game.dll and replace this one.

Compatibility:
This is a modification of the original Game.dll and it can be used along with any other mod out there that doesnt touch this file but i suspect some mods that alter Vanilla Items or User Interface may cause some CTDs. I cannot fully test this with everything please give feedback.

Additional Notes:
In my opinion Titan Quest is a bit biased towards Rare items leaving little room to customize Epic and Legendary stuff. This mod aims to change that and give access to more options when it comes to gameplay and character build. There are few files provided: A main file for the latest version of the game and some files for older versions just in case if some people didnt update their game to the latest version. TQ AE will probably get more updates in the future which will change the .dll structure as well me thinks so if its the case i will also update this and upload it on Nexus.

Changelog (22.10.2022):
The mod have been updated to Titan Quest Anniversary Edition Eternal Embers v2.10.21415 and previous version moved to Old Files section.
