Aside from mental fortitude a necessary component is vitality. The raw force of life and power itself,
seen by some cultures, like the Taoists, Tibetans & Lakota, as lightning (and the latter most with
horses as the earthly animal totem thereof). Funny enough though we have this ancient Aryan concept
of Lightning war, Vajra(kilaya), Thor, Blitzkriege, Umman, or even Gangis Khan coming from nowhere with
irresistible force (no electrical impedance could suffice). And so the less conductive elements must
bow, by axe, horse, spear, or literal electrical god-like presence that makes fallen men not even dare
to try disrespecting an obviously superior hero/demigod.

This is getting on track, I promise though first I must give appropriate mythological context for the unlearned.

Lightning, or more formally now-a-days, electricity. Is the supremely unconquerable element, like fire,
but higher order and not quenchable by water, infact the reverse may well be true (flash boiling of water
or other electro-repulsive effects). In other words the air (O2), water (H+HO), move as an electrical
response to lightning, or even on small scales, bio-electricity or chi. When you move elements you are
their lord, you by force of will commandeth, not by hammer nor blade but pure creative imagination, vital
desire, and vivid focus. This will make flows that carry the earth (heavier minerals, salts, and very
importantly, metals). Any how, the water moves always, it's currents, both of emotion energy and literal
water, within (blood, flesh, bile, etc) and without (rivers, clouds, wells) conveys magnetic charges
bother measurable and most importantly cultivatable!
