* 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.

* Enfeeble can be used to decrease Shadow Fiend's already abysmal level one damage even further, preventing him from getting farm and Necromastery stacks.
* Brain Sap allows Bane to heavily harass Shadow Fiend.
* Nightmare allows Bane to set up some early ganks onto Shadow Fiend.
* Fiend's Grip enables Bane to completely take Shadow Fiend out of a fight and potentially even kill him, even through Black King Bar.

* Heroes that wish to disrupt fights with spell combos or big ultimates are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* 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 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.

* Heroes that wish to disrupt fights with spell combos or big ultimates are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* Heroes with spell immunity can still be disabled by Fiend's Grip: Juggernaut, Lifestealer, Pangolier.

Additional:
* Fiend's Grip can disable Lifestealer through Rage.

* 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.

* 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.

* 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.

* Enfeeble, Nightmare and Fiend's Grip all prevent Legion Commander from winning Duels, especially when Bane has Blink Dagger.
Additional:
* Bane has powerful single-target abilities that can help his allies win Duels, or at least cripple Legion Commander for the duration.
* Nightmare can waste Duel's entire duration as the dueled units transfer the Nightmare back and forth. This may be prevented if a non-Dueling unit attacks the Nightmared Dueler.

* 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.

* Fiend's Grip provides mana drain, which can heavily damage Mana Shield and prevent Medusa from using Stone Gaze.
* Even if she does use Stone Gaze, Nightmare can buy enough time to protect allies and reset the fight.
Additional:
* His Fiend's Grip will leave Medusa defenseless after he's done, if his teammates can provide cover for him or he initiates at the right time by Spell immunity.

* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage

* 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.

* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Luna, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.

* Brain Sap's magic damage ignores stacks of Reactive Armor.
* Nightmare prevents Timbersaw from using Timber Chain, setting him up for chain stuns and burst damage.
* Fiend's Grip immobilizes Timbersaw and drains his low mana pool, preventing escape afterwards. It also pierces Black King Bar.
* Bane's multiple disables often force Timbersaw or his teammates to spend gold on a Linken's Sphere.

* Fiend's Grip's very long disable prevents Anti-Mage from Blinking away or using Manta Style. It also pierces spell immunity.
* Nightmare sets Bane's team up for chain disables on Anti-Mage.

* 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.

* Bane can also prevent Brewmaster from using Primal Split with his long disables.

* Fiend's Grip and Nightmare are very useful to lock down Void Spirit.
* Brain Sap can be difficult for Void Spirit to deal with in the laning stage.

* Heroes who possess abilities that can save targets from being killed by Reaper's Scythe: Abaddon, Bane, Outworld Destroyer, Shadow Demon, Omniknight, etc.

* 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.

* 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.

* Nightmare and Fiend's Grip help to control/disable Troll Warlord in team-fights.

* 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.

* 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.

* Bane's Enfeeble makes Ursa more susceptible to disables as it reduces Status Resistance.
