Thank you everybody. Your words of wisdom and advice have been very helpful and now I have combined many artifacts and have won many games because of it. Thank you...
If you have complete, sod or ab then the best way to learn about comining artifacts is to go into your map editor exe.
Once there you click on the tool bar for artifacts and you will see a box on the right with pictures of all artifacts.
Scroll down until you get to the main relics and then just right click on the one you want to look at , and you will be given a list of which items you need to build it.
Hope thats helpful
