Twilight's godslayer spell in that fic was, for lack of a better term, awesome. I never speculate before then there would ever be a magical version of a magnetohydrodynamic weapon appearing in fantasy fiction.

There are few things in the universe that could withstand the impact of a projectile travelling at near the speed of light. Especially if said projectile is a hyper-velocity stream of highly energized molten metal.

Woe to all and any on the receiving end.
