stormlord 'elemental strike'
Stormlords are masters of the elements, surrounding themselves with burning fire, freezing cold or devastating lighting, and imbuing their attacks with the same deadly elemental powers. The elemental strike skill adds additional elemental damage on each hit, but at a substantial mana cost (2 + 0.2% of current mana per hit, 2d10 damage per mana). Once mana drops below the calm threshold, elemental strike deactivates. When combined with the elemental blade stance, it instead increases the elemental damage dealt by level/2, at no extra cost.
