Dota 2/Luna the Moon Rider

Luna is a ranged agility hero who is usually played as a hard carry. She can deal damage among multiple enemies with her Moon Glaives, while having greater night vision with her Lunar Blessing. Her Lucent Beam is her staple damaging ability that can be used to disrupt channeling abilities, and she can summon tons of them with her Eclipse ultimate.

Lucent Beam
Lucent Beam makes a beam of moonlight stike the target, dealing damage as well as mini-stunning. A good single target ability that does decent damage. Its mini-stun will be valuable for stopping channeling spells and teleports. With a mere cooldown of 6 seconds, it can be quite spammable, but you don't really have a large mana pool without items. It should also be noted that the level of your Lucent Beams with directly influence how powerful your ultimate is.

Moon Glaive
Moon Glaive makes your normal attacks bounce between enemy units nearby the unit you're attacking. Each bounce deals less damage.

Eclipse turns day into night for 10 seconds before randomly striking enemies with Lucent Beams, dealing damage equivalent to your current level of Lucent Beams but doesn't mini-stun.
