Sun

Enemies hit by Sun and his Doppelgangers will have their Physical Defense reduced by 5% (stacks up to 6 times). Sun recovers HP equal to 75 plus 25% of the Doppelganger's Physical Attack each time a Doppelganger deals damage.
Sun and his Doppelgangers' Basic Attacks deal 50 extra damage to Creeps.

Sun hurls his Golden Staff in the target direction, dealing 200 (+40% Total Physical Attack) Physical Damage to enemies in its path. Upon hitting an enemy hero or Creep, or reaching the maximum range, the Golden Staff morphs into a Doppelganger that lasts 5s and inherits 40% of Sun's attributes (and a portion of his Attack Effects).

Endless Variety and Swift Exchange are learned and upgraded together and share the same cooldown.

Sun hurls his Golden Staff in the target direction, dealing 200 (+40% Total Physical Attack) Physical Damage to enemies in its path.

Sun commands his Doppelgangers to strike at the target enemy with him, dealing 270 (+40% Total Physical Attack) Physical Damage and slowing the target and enemies behind them by 20% (can be stacked) for 1.5s. This counts as Basic Attack damage and can trigger Attack Effects but cannot Crit.

Sun summons a Doppelganger that lasts 8s and inherits 70% of his attributes and a portion of his Attack Effects. The Doppelganger takes increased damage.
