In my game world of Ashen Grey sometimes magic becomes so powerful in an area it crystallizes into a substance known as Residium. This gem has amazing properties including empowering spells, enchanting items, and in rare cases making magic permanent. Needless to say it is a rare resource that players quickly begin wanting to hoard and use to their own means, however Residium the grows naturally has one more side effect. It warps creatures that make their lairs near and around Residium.
One Example is the Mana Stirge which appears to be the same as any other stirge but rather than sucking blood it instead drains magic. These can be much more of a nusance than normal sturges as well since if a target doesn't have magic they instead resort to feeding on a character's life force.
As dangerous as those sound though my other offering is even worse. This can either be a massive threat or even just a way to rein in a party that's ended up with too much loot. The residium monster is the magical equivalent to the dreaded rust monster. Plain and simple this beast devours magic items. I will warn that if your story doesn't call for this guy to show up your players will be calling shenanegans left and right so if you really want to use it find your place to have it make sense then watch them squirm. (Sadly I haven't worked up a Savage Worlds stat block for this guy, but if I finish him at any point I'll release it for all of you).
