Right, this is an idea that's been in my head for a while.
Now, I'm unaware how different that Dread Elementals are combat-wise in comparison to regular elementals. But I do know that they look pretty badass. Kudos to the one that designed them.
Far as I know, the lore is that it's an corruption of an elemental summoning spell, and when done accidentally, the elemental is free-willed and tries to kill it's creator. That's fairly known.
But....What if it's done on -purpose-? Could a mage then bind it to service? It seems like a cool concept. And a solid incentive to actually take the feat Augment Elemental.
But I hear the nay-sayers : ' Oh, Ken, you want to give the wizards more tools to be overpowered'? Well, I shan't deny I would like them to have a cool new means to be awesome, sure.
However. Dread Elementals are still, y'know. Dread Elementals. No run of the mill mage (even an experienced one) could hope to pull that off successfully.
So, I'd say, you'd need to be -specialized- in Conjuration to actually have a chance. And probably not all that sane, to be honest.
I'm not gonna eke out details just yet, because the answer to this suggestion may very well be a resolute No. Or a 'this needs to be done through Roleplay, not a restricted class feature', which is just as fair. Might make a Conjurer just to see if it could be done!
Still, though. You're locked out of Transmutation spells if you become a Conjurer. That's in itself a rather radically different way of playing a wizard, as buffing becomes difficult.
It seems like a fair trade-off if a specialist of conjuration could actually pull off controlling something that tends to go bananas when any other mage tries it.
But that's my suggestion. Thoughts?
