Are they remotely lore-inspired?
Fury of the Wolf Spirits - The Rune Priest summons up the spirits of the Thunderwolves Freki the Fierce and Geri the Cunning from the netherworld. These Thunderwolves were Primarch Leman Russ's wolf-brothers and constant companions. The Rune Priest sets the charcoal-black spirits of the two most exalted Thunderwolves upon the foe, their eerie howls sending men mad with fear. As long as this power is sustained, the Rune Priest is flanked by two spectral wolves that he may direct against his foes with a verbal command.
Jaws of the World Wolf - The Rune Priest implores the spirit of the world upon which he walks to open its rock-fanged maw, and a chasm cracks open under the feet of his enemies, sending them tumbling to their deaths.
Living Lightning - The Rune Priest cries out to the sky and calls a dancing bolt of sentient electricity down from the heavens. This bolt crackles from the brooding skies, arcing into the ranks of the enemy and grounding on foe after foe until a trail of blackened corpses is left in its wake.
Murderous Hurricane - The Rune Priest bellows an ancient curse and his frosted breath coalesces and grows into a deadly blizzard. Within moments, the Rune Priest's foes are all but consumed in a hurricane of freezing shards, a thousand blades of Warp-forged ice plunging into their flesh.
Storm Caller - The Rune Priest chants an ancient rite that builds into a terrifying crescendo. In the space of a few moments, howling winds and furious blizzards rage about him in a vortex of ice and snow that crackles blue with destructive psychic energy.
Tempest's Wrath - In a fearsome display of power, the Rune Priest calls upon the spirits of wind, storm, and snow, tearing the air with gales and tempests. The Rune Priest brings the rage of the storm to a roaring climax as frost-fingered wind spirits whip those who intrude upon their domain out of the skies and smash them upon the stony ground.
Thunderclap - The Rune Priest slams his armoured gauntlets together whilst shouting a word of power, and the noise is magnified a hundredfold. The resultant thunderclap is loud enough to shatter stone and even liquefy the brains of those nearby.
