* Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.

* Provided Luna is able to cast it in time, Eclipse can help win a Duel from Legion Commander.
* If Luna isn't the target, she can easily use Lucent Beam and Eclipse to win the fight for the ally.
Additional:
* A well-timed Eclipse before a Duel usually prevents Legion Commander from winning Duels, if Luna is the target.
* Meanwhile, when Luna is not a target, Eclipse and Lucent Beam can also help an ally win a Duel against Legion Commander.
* However, skilled Legion Commander players will always have a Black King Bar or Aghanim's Scepter handy since both abilities do not pierce through spell immunity.

* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and Dazzle.

* Moon Glaives is effective at destroying Familiars and will remove one instance of Gravekeeper's Cloak upon each hit to Visage, leaving him susceptible to damage.

* Though Luna has a hard time laning against Necrophos, his Ghost Shroud won’t protect him in teamfights because it will increase the damage from Lucent Beam and Eclipse.

* Dazzle's Shadow Wave is a spammable healing ability that spreads around his entire team, slowing the death of his teammates as effectively as Necrophos spreads damage to them.
* If not immediately, Shallow Grave delays his ally from gradually dying to Necrophos' abilities, especially Reaper's Scythe.
Additional:
* Reaper's Scythe is very predictable and gives you plenty of time to react with Shallow Grave: just keep a close eye on allies below 50% health.
* However, be sure to use Shadow Wave on that ally immediately after, or they will die from Heartstopper Aura when the Shallow Grave ends!

* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden

* Heroes who continue dealing damage while being stunned: Luna, Razor, Axe, Bristleback, Leshrac,

* If Luna can use Eclipse in anticipation, Magnus will be killed before he can even manages to cast Reverse Polarity.
* Aghanim's Scepter upgraded Eclipse is a very good counter-initiation tool against Magnus when he casts Reverse Polarity, granted as long as Luna can cast it from safe distance.

* Lucent Beam and Eclipse with ministun talent can be used to cancel Requiem of Souls if Shadow Fiend does not have Black King Bar.
* Moon Glaives and Lunar Blessing allow Luna to outfarm Shadow Fiend in lane.
* A well timed Eclipse will burst and kill Shadow Fiend before he even gets a chance to retaliate, especially when equipped with Aghanim's Scepter and Ethereal Blade, this could become even worse for Shadow Fiend if he does not have Black King Bar.
* Even though Shadow Fiend can evade all of Luna's abilities with Shadow Blade, a smart Luna will always buy Dust of Appearance to provide vision on Shadow Fiend to her and her team.

* Shallow Grave saves an ally whom Terrorblade has used Sunder on.

* Heroes that can stall pushes: Invoker, Keeper of the Light, Lina, Luna.

* Lucent Beam interrupts Death Ward from a decent range.
* Eclipse kills Witch Doctor during Death Ward, even through Glimmer Cape.

* Aggressively blinking is not going to end well against Luna, because Queen of Pain will be an easy target for Lucent Beam & Eclipse.
* Queen of Pain's HP is abysmal, so Luna can quickly kill Queen of Pain as soon as she initiates with Blink.

* Guardian Angel does not offer protection from Eclipse, though it will negate damage from Moon Glaives.

* Although he can avoid Eclipse with Rage and Infest, Luna's physical damage can be enough to deal with him.
* Manta Style is a common pick on Luna, which can help her dispel Open Wounds. In addition, Lifestealer is not good against illusions created by Manta Style.

* Cold Embrace is no salvation against Lucent Beam and Eclipse.
* Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by Lunar Blessing than Winter Wyvern when affected by Arctic Burn.

* Luna has better night vision provided by Lunar Blessing than Winter Wyvern when affected by Arctic Burn.

* Lucent Beam allows Luna to easily cancel Freezing Field.
* Without Black King Bar protection, Lucent Beam and Eclipse can make a short work out of Crystal Maiden's abysmal health.
* Skilled Luna will always buy Dust of Appearance, allowing her team to have a vision on Crystal Maiden while invisible and during channeling Freezing Field.

* Venomancer's damage-over-time abilities are easier to heal through with numerous Shadow Waves than other types of damage, and it's simple to time a Shallow Grave until the last possible second to save a teammate from them.

* Luna has Moon Glaives and Lunar Blessing to help her destroy Tombstone, and this becomes more effective if Luna is equipped with Manta Style.
* Defending with Zombies from Tombstone against Luna is not a good idea because Eclipse will strike only Undying.

* Lucent Beam can cancel Tether and Relocate.
* Moon Glaives and Eclipse make short work of Io and its tethered ally.

* Lunar Blessing gives allies bonus damage and armor required to endure against Atrophy Aura early on.
* Eclipse can be devastating for Underlord's team when they're grouped up for Dark Rift, it can also be used to intercept arrivals with Dark Rift. And Pit of Malice does not prevent Luna to use it.
* To make things even better, Aghanim's Scepter upgraded Eclipse can finish off Underlord or any of his teammates escape attempts with Dark Rift if timed correctly.

* Moon Glaives can easily clear Chen's creeps while Eclipse can kill Chen's allies before he can react.
Additional:
* Luna's Moon Glaives and Lunar Blessing can easily kill Chen's creeps.

* Hand of God has a long cooldown, so damage over time spells can be hazardous for Chen, forcing him to use it prematurely: Jakiro, Venomancer, Viper, Dazzle, Phoenix.

* Life Drain will be always canceled by Lucent Beam if Pugna does not have Black King Bar.
* Decrepify can be suicide against Luna due to Lucent Beam and Eclipse.
* Nether Ward is rather weak against Luna since she does not have abilities that cost a lot of mana.
Additional:
* Luna can shrug off most damage taken from Nether Ward as she only has two castable skills with average mana cost.
* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Lucent Beam's considerable range can reliably cancel Pugna's Life Drain.
* Luna is a common Black King Bar carrier, which totally nullifies Pugna's damage output.
* If Pugna uses Decrepify on himself to avoid Luna's right click, she can burst him down with Lucent Beam and Eclipse.

* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.

* Luna can easily prevent Tinker from escaping with Boots of Travel or Rearm with Lucent Beam.
* Luna can also quickly tear Tinker to shreds with Eclipse as soon as he jumps in with Blink Dagger.

* Even though Luna is the kind of hero that Bounty Hunter can handle due to Shadow Walk rendering him safe from Eclipse, smart Luna will always buy Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.

* Without Black King Bar and if not caught in it, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam.
* Moon Glaives combined with Lunar Blessing can make a short work of Enigma's Eidolons.
* If used in anticipation, Eclipse will often kill Enigma before he even gets a chance to use Black Hole to disable Luna.
* Luna has stronger laning presence than Enigma thanks to her Moon Glaives and low mana cost of her abilities, diminishing Enigma's laning presence by a lot.

* Luna's Lucent Beams and Eclipse will prevent Earthshaker from initiating or re-initiating.

* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.

* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.

* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: Brewmaster, Dazzle, Tidehunter.

* Moon Glaives and Lunar Blessing help Luna to tear off Nature's Prophet's treants.
* Luna can easily cancel Teleportation with her Lucent Beam.

* Enchantress has pitiful HP so Lucent Beam and Eclipse can kill her very quickly.
* Moon Glaives allows Luna to clear Enchantress' creeps very efficiently.
Additional:
* Enchantress has pitiful HP, even more pitiful than Luna, so Lucent Beam and Eclipse will often harass and/or kill her through her Untouchable.
* With Moon Glaives, Luna can clear Enchantress's creep wave efficiently.

* Luna can push very fast with Moon Glaives, which is something Riki cannot deal with well.
* Luna is naturally very fast, making it hard for Riki to trap her in Smoke Cloud.
* Even though Riki can evade Eclipse with his invisibility, smart Luna will always buy Dust of Appearance, providing vision on Riki to her allies and herself.

* Luna often builds Black King Bar, and none of Tidehunter's spells can bypass spell immunity.

* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.

* Luna's Moon Glaives allow her to clear Arc Warden's Tempest Double.
* Luna's short range and fast movement speed allow her to fight Arc Warden inside his Magnetic Field.

* It is almost impossible for Bane to use Fiend's Grip properly against Luna's allies due to the huge cast range of the Lucent Beam.
Additional:
* Luna's Lucent Beam can be used to disable Bane while he is channeling Fiend's Grip.
* Luna's Eclipse will often be able to kill Bane before he can even act.

* With Dust of Appearance, Luna will be able to use Eclipse on invisible heroes. Be mindful that Slark is exception because he'll be able to remove the debuff with Dark Pact.

* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, Abaddon

* Any hero that can nullify effects of Chronosphere: (Omniknight, Keeper of the Light with Aghanim's Scepter during daytime, Winter Wyvern), banishing him or Faceless Void (Outworld Destroyer, Shadow Demon, Earth Spirit with Aghanim's Scepter) or protecting him in other ways (Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.

* Heroes with the ability to heal allies, or those with good defensive abilities: Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.

* Shallow Grave can be used to save an ally during Dismember and Rot.
