Wheel of Nine Heavens Rune (IV)

+100% Special Ability Damage.

Sacred Orbs conjures one additional orb.

When a Sacred Orb's time runs out it no longer fades. It breaks orbit, streaks to the nearest enemy and bursts for 300% weapon damage as Lightning damage in a 3m radius. (300% weapon damage at Sacred Orbs level 1, 310% at level 2 and 10% weapon damage more for every further level.)

Each cleared boss encounter of level 40 and higher has a 2% chance to drop a rune (1.5% on mini-boss stages). On Inferno 0.5% of those runes are Set Runes before the stage's loot bonus and Item Find, which raise it; on Normal and Nightmare no Set Rune drops. Only runes for the current hero's class drop.
