Spell Eating is something I considered, but the concept of eating means that it takes the magic in, ostensibly for use of some other effect.
Part of that would be for the purpose not of taking the
Winds of Magic in... ... but of
channeling the Deep Magics of the Earth.
Which, uh, I guess makes the "for some other effect" part to be "the effect of Spellbreaking". And maybe MCurrents. So yeah. The Spelleating is there to channel the deep energies of Barak Azamar, its Conduit of the Earth.
To pit the energies of the
Earth, against the energies of the
Wind.
Though, yeah, Spelleating may not be the
exact best for this, but... Not exactly sure what rune to use for this...
Though now that I spoke it aloud like this, "To pit the energies of the
Earth, against the energies of the
Wind.", I now want to see it happen via Theme or Function write-in... ... Yesss. Now that I say it like that... I do want to see this happen. I want to pit the mountain, against the wind! I want the Axe of the Mountain! Which cuts apart the very Winds of Magic themselves!
... Mrgh. That basically means I just want, what you were describing -- a very cutting axe, which cuts magic --
buuut I want assurance that it'll do so via a connection to Barak Azamar and its Conduit of the Earth, as the method and connection... How to accomplish that?
(Also, huh, having described it like that... ... *looks at Kholek's brain description*)
[Tier 5] The Suneater's Brain x1: The dead mind of one who saw the pact of the foulest kind be struck between primordial beast and dread thing beyond the veil of reality. The conscious and the evil has left, but the brain matter is potent regardless.
(... I wonder if this would work as a Master Rune of Currents replacement? A Rune Ingredient that would REALLY let you target the Winds. Because you could really, really, see the Winds of Magic.)
(... Gah. No, not quite perfect fit...) (Also, so many other things that it could do. For instance, it could be some kind of Anti-Chaos weapon, rather than just Anti-Magic. Or maybe some kind of intelligence, or scanning ability, or... I dunno. Something.)
(... It'd be perfect if we could use a Branakokri Brain. Except that. Um. That's gruesome. That's the dead body of a friend and ally. A thinking being. And like... even if we did have a dead Brana to use, that's... I don't think that would be right. Just. Ergh.)
(Dammit, if only we had another Elder Dragon Brain. That seemed to be a replacement to the Griffon Brain for the MCurrents rune on the ballista bolt, right? At least, it seemed to have worked out, right. Hm. Do we know if Dragon Ogre Shaggoth Brain could also suffice?)
EDIT: I guess we could try to pivot to the Master Rune of Smiting, as we have the Elder Thundertusk's Tusks, which are Tier 4 upgrades to Stonehorn's Horns, which is for MSmiting. But if you're doing that, then you're pivoting away from MCurrents entirely, in order to go for a Magic-Smiting build. Which, fair enough, might work. But it's, well, it's not the same
theme anymore. It's not using MCurrents anymore. Bah.
