The mana crystal gave her an ability on par with Invigoration, but after using it so many times on so many people, it had lost most of its effectiveness.
On top of that, the orc shaman was running on fumes and her stamina had hit rock bottom. Light magic had healed her wounds but without food, her body couldn't make up for the lost nutrients.
Ryla inwardly prayed to Glemos to forgive her for her transgression and then used her wings to draw in the bulk of the energy wave before it was too late. The combined efforts of the orc's crystal and the Fomor's wings overpowered the Hands, filling Ryla to the brim with elemental energy.
Her wings burned like multi-colored blazes while her eyes shone like suns as she focused and amplified the power of the elements with every bit of mana she had left.
