You're just ahead of me. I stumbled upon a pretty scary Karavox with a 106 attack. This stacking is insane. And worse there's no way to dispel these buffs. It's probably good ai play, but it's over the top. Just like Dirge of Cersesa. My first time using this spell I killed a complete field of deadly opponents guarding a dragon eye. I was chanceless and my army got slaughtered, but Dirge of Ceresa killed them all in almost one blow. The rest was sone the next turn thanks to poison. I'd say the beta needs some more balancing!

I agree.  The AI is probably just taking advantage of this ability to stack enchantments.  Now there are mana upkeep costs, and you would need a healthy mana income to keep those enchantments up....but still I don't think it should be allowed to stack the same enchantment so many times. At the very least the mana upkeep should be compounded exponentially per enchantment.

I don't think enchantments should stack AT ALL.
