- Assembled artifacts in Heroes 3.

What's there to discuss about the most overpowered artifacts: King of the Undead's Cloak, Sniper's Bow, Elixir of Life, Mage's Ring. The rest don't offer any significant advantages.

So, the Expert Prayer from the Angel Alliance, 4 negative spells from the Cursed Armor, and magic immunity from the Power of the Dragon Father – you don't consider those advantages?
And what's the advantage of the Mage's Ring? +50 rounds to the duration of spells is useless; battles don't last that long anyway.
