Some observations:

Armageddon Lasts for multiple turns, which is why it's so evil. I was playing with some friends and one cast Armageddon, but the game was pretty much wrapped up at that point already. So I'm not sure how long it Lasts. 3+ turns anyway. Since units die off randomly (even pretenders!), it may stop when the caster gets waxed.

I need to do some more testing on it, but Forge of the Ancients seems to halve the gem costs, NOT give 50% forge bonus. Dwarven smith with Forge Lord hammer (75% total bonus) uses 10 gems (25% of 40) for a Robe of Invulnerability.
