Got a great laugh on this one! Awesome meme man. Yeah it's legal in the way you showed it was. Most players dont have more then 1 amulet and they usually cast it at the beginning of the game so its a fun strategy. They usually just dissolve it though
I'd be happy if they have to waste a Dissolve to get rid of an EoB to stop the hurting. Small wins.
Are we absolutely sure it works? EoB keeps referencing "you" and "your Mage." Is that the Mage it's attached to or the Mage that controls the spell? I can't remember if somewhere it states that those are the same for equipment (unlike Enchantments and Conjurations).
The reason I'm asking is that my Sectarus-based direct damage/curse AC Warlock guffaws at the idea that his [mwcard=MW1J04]Battle Forge[/mwcard] can now cast a pseudo-curse on his non-Dark opposing Mage that might use up a Dissolve that would otherwise be saved for a much more crucial equipment on my Mage. Sure, it's just a Curse of Decay that can target a Mage... but hey, it's a Curse of Decay that can target a Mage that can be cast by Battle Forge!! (And stacks with Magebane and Ghoul Rot and Plagued and all the rest)
Also... I'm now officially campaigning to get the Curse subtype put on EoB. I mean, even when it targets your own Demon-based Dark Mage, it's obviously a curse. It's certainly as much a curse as Demonic Bloodlust and the promo Bloodthirsty Strike.
