1. The key phrase is that you got a little lucky at the start.
Yesterday, in 6 out of 7 dungeon runs, I took gold, sulfur, and crystal mines, and a dragon lair on days 7-8. Once, I got them on day 5 (I was lucky that golems were guarding the crystals, and I took them with a hero with one Fury).
You won't be able to defeat 7 stacks of 7-15 Alt Golems before the hero's turn.
And after the hero's turn (Armageddon), all the golems are alive again, and at least 1-2 stacks will survive until their turn.
Of course, Golemodon is strong, but not invincible. But for Razazak with Battle to the Last, it definitely makes sense.
If you don't attack the golems before the hero's turn:
a) before attacking the golems, you get a gem before your turn, and if you're lucky
b) with Expert Enchantment, you can get a second gem, and at least one of the two will be lucky. In total, about 3,000 damage per stack, and the golems are still in full force. You can even defeat the main hero with his entire army this way.
1. Even with Enchantment, the hero won't go twice before the initiative troops. And those troops may also have artifacts.
2. Half of the golems may be gone even before the hero's turn.
3. 1000 damage from Armageddon without luck = 32 spell power. It's hard to believe.
