    I would like to play this mod. but autocasting artifacts are killing me, you can literally never visit mage guild or heck why even bother to buy spellbook. Is there a way to remove/disable those artifacts?
    Would much apreciate for answer, other than that great mod keep up 🙂

    1. Perry

      You can change the properties of artifacts in a .txt file in the mod folder. Another option would be to disable all new artifacts by disabling the Emerald plugin. This will leave you only with the H3/WoG artifacts.

      1. Secondall

        That a good one mode, but i suppose, will be a good idea to add some changes in creature specialists, 7+lv specially. For example Xeron can give his devils/archdevils not only a 5/5 attack and defense statically, but act like others specialists, and improve them (and hellbarons 2 upgrade with antichrists 3 upgrade) as he reaches the high level. So same about Mutara, Killgore, they can too improve their spec creatures, from red dragon to chasm dragon etc. And on the other hand is Dracon and Gelu, they can be some new kind of specialists. Or not. However, T7 creature specialists are really need to be changed.

    Thanks You Perry.

    That’s great we can now upgrade 7th unit to 4th upgrade in town, but they cost less then 3rd upgrade so it’s pointless to buy 3rd lvl. Is this a bug or it’s only me?

    I dont know where to ask this question so i`ll ask it here, is there ANY way of fixing slow AI ? I have tried playing G H XH maps with 4 or less AI enemies and after month 3 the game becomes unplayable. The issue occurs even with a single AI enemy.

    What i believe the fix to be is limiting AI to a fixed number of maximum heroes or removing the two way portals all together, or somehow limiting AI`s ability to spam those portals.

    Can anybody help? I cant believe there`s such a richness of content yet nobody has adressed this issue yet.

      Hi, this problem occurs when the AI starts using the Dimension Door spell. You can prevent this by finishing the map faster 🙂 or remove this spell from the game (also artifacts that contain it):

    This seems to be a bug, i`ve noticed it yesterday with Titans.

  6. illudere

    Hey, thanks for answering. I tried disabling DD with WOG options and pre-game options from the advanced classes mod (i believe) but that didnt seem to solve the issue. I cant be 100% sure if the options went through since i had alot of mod running at the same time , probably some conflict somewhere.

    I`ll fresh reinstall and give it another go. Tx again.

    1. Perry

      the long AI turn unfortunately is a bug from the Third Upgrade Mod. Sometimes it happens, sometimes not. The author is aware of this problem. When there is a definitive solution we will let you know.
      Also please use the latest TUM v2.12.6

    Hi there, I wonder if there is a Creature list with the assigned numbers for the new amethyst creatures?
    Thanks Tom
