Luna build & guide (7.41)

Lucent Beam

Calls a beam of lunar energy down upon an enemy, damaging and briefly stunning them.

Aghanim's Shard: Grants Luna an attack damage bonus buff every time an enemy hero is hit by Lucent Beam. Lucent Beams created by Eclipse grant 0% of the damage amount.

Lunar Orbit

Creates 4 glaives that rotate 225 radius around Luna. Any enemy unit that collides with a glaive will take a percentage of Luna's Attack Damage.

Aghanim's Shard: Increases damage reduction. While active, Luna gains 20% bonus movement speed.

Moon Glaives

Empowers Luna's glaives, causing her attacks to bounce between enemy units. Deals less damage with each bounce.

Lunar Blessing

Grants attack damage to Luna and nearby allied heroes within 1200 range, with Luna receiving double the attack damage bonuses. At night, Lunar Blessing is global, and Luna is blessed with bonus night vision.

Eclipse

Showers random nearby enemies with strikes from Luna's current level of Lucent Beam. These beams do not stun their targets, and there is a maximum number of times that a single target can be struck. Also turns day into night for a short time.

Aghanim's Scepter: Allows Luna to cast Eclipse on an allied unit or herself and have its effects follow them, or cast it on an area. Increases total beams, reduces duration, removes the limit on beams per unit, and makes the beams appear twice as fast.
