Can you even stab the stormfather? And even if you could, I doubt a single spike can hold enough investiture for that.
I'd doubt it, I don't think you can target specific powers with aluminum spikes. But who knows, maybe ypu can with the right technique.
Maybe?
Good luck then, Bondsmiths can naturally compress time 15 to one, with a Dawnshard I'm going to easily outpace even compounded steel with savanted bendalloy.
*Exists hyperspace behind you* "Nothing personal."
We don't know enough to include them yet.
Dawnshards require another set of invested abilities to work, while they will give some benefits, like noticing colors or tastes better, on their own you can't do things like crack planets or whatnot.
