* Every ability Witch Doctor has is useful when Rubick manages to steal any of them:
* Paralyzing Cask provides an additional disable apart from Telekinesis and also helps Rubick to farm.
* Voodoo Restoration provides utility by healing Rubick and his team, since he has no heal of his own.
* Maledict is a solid damage-over-time nuke, which can be devastating to the enemy team.
* And most importantly, Death Ward is one of the best teamfight spells in the game. It also requires channeling, which makes it easy for Rubick to steal. And when combined with Aghanim's Scepter, this can prove deadly to the enemy team.
* However, a skilled Witch Doctor will always toggle Voodoo Restoration while channeling Death Ward to prevent that.
Additional:
* Rubick can steal Death Ward easily as it is a channeled ability and then use it to turn teamfight to his advantage.
* However, a skilled Witch Doctor will toggle Voodoo Restoration immediately after placing his Death Ward to prevent that.

* Lucent Beam is a solid magic nuke.
* Eclipse can cause massive damage if cast in the right time.
* Rubick has a good chance to steal Eclipse for Luna has only two cast abilities.
* Aghanim's Scepter greatly increased the effectiveness of the ability, including more damage as well as longer cast range. In addition, it allows him to cast it on another hero so Rubick doesn't have to get close to the enemy team in teamfights.

* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.

* Her Spiderlings can harass Luna in lane heavily, as Luna has no AoE abilities to clear Spiderlings.
* Broodmother can knock down towers in the early game quickly, and limit Luna's farming space.

* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.

* Sacred Arrow can be used to interrupt Death Ward from a safe distance, forcing him to cancel it to dodge or get hit.
* Paralyzing Cask is a slow-moving stun, and Mirana can Leap away from her allies to keep it from bouncing.
* Witch Doctor has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Devourer.

* Beware of placing the Death Ward if Chronosphere is off cooldown, as it will cancel the effect and leave Witch Doctor vulnerable if he does not react in time.

* Lina has very high magic burst damage to use against the low-health-pool Luna. Laguna Blade can also be upgraded with Aghanim's Scepter to bypass Luna's Black King Bar, making Lina even more of a threat.

* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.

Additional:
* Light Strike Array cancels out Death Ward from a long distance.

* Flesh Heap's magic resistance allows him to survive Eclipse, and Meat Hook and Dismember can disable Luna through her Black King Bar.
* However, Lucent Beam can still cancel Dismember from a safe distance, even if its damage is going to be reduced.
Additional:
* Pudge can easily survive Luna's Lucent Beam and Eclipse, and his Meat Hook and Dismember can pierce Black King Bar, making Luna one of the perfect victims for ganking.
* However, Lucent Beam can cancel Dismember, as Pudge often doesn't build Black King Bar, and if she is farmed enough, Luna might be able to fight back against Pudge.

* Heroes that have a channeled ability can be interrupted by Meat Hook: Pugna, Witch Doctor, Enigma, Bane.

Additional:
* Meat Hook interrupts Death Ward from a decent range, even through Black King Bar & Glimmer Cape.
* Pudge can survive the damage from Maledict because of his Flesh Heap stacks.
* However the damage-over-time from Rot is counteracted by Voodoo Restoration.

* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna

* Sniper usually sits at the back and it's hard for Luna to get close to him to attack.
* Due to Sniper's Shrapnel and his long range, Luna has a hard time taking high ground despite her Moon Glaives being fantastic for taking Barracks and buildings.

* Death Ward's first target (before it bounces) can evade it, therefore Windranger and Phantom Assassin are poor choices to use it on.
* However, once the first hit landed, the bounces can no longer miss. Don't forget to manually aim for a target with no evasion !

* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa.

* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.

* Hard-hitters who relies mostly on raw stats or good passive and therefore make a perfect target for Dark Portrait: Naga Siren, Faceless Void, Terrorblade, Luna, Anti-Mage

* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.

* His highly damaging nuke spells with low cooldowns is not something Luna wants to go against.
* Thundergod's Wrath can be used before a fight to harm Luna before she activates her Black King Bar, reducing her survivability for that fight.

* Wraithfire Blast cancels Death Ward in decent range.
* Death Ward is meaningless while Reincarnation is off cooldown.
* Vampiric Aura can out-heal the {tooltip:DoT|Damage over Time} from Maledict.

* Because of her low range, Luna cannot easily destroy Healing Ward.
* Both Blade Fury and Omnislash are direct counters to Eclipse, offering Juggernaut spell immunity.

* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with Fate's Edict and Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with False Promise.

* Like any hero with a channeled spell, Last Word is a counter to it.
* Global Silence goes through spell immunity and prevents Witch Doctor from casting his spells.

* Luna has low HP, low range and often stalks through jungle. She cannot properly disarm Proximity Mines and could fall victim to their traps.
* Of course, if Luna happens to catch Techies off-guard, they won't be able to survive for long against Eclipse, Lucent Beam, and right-clicks.

* Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from Maledict.

* Meepo can tank Eclipse because of his clones.
* Earthbind takes away Luna's mobility advantage.
* Meepo can shutdown Luna's split-push ability with his global presence.

* Morphling can Attribute Shift to strength after being hit by Maledict. Since Maledict deals its damage based on the difference between HP on cast and HP after two seconds, odds are Morphling will have more HP than when Maledict was cast, thus resulting in no damage.
* On the upside, players prone to panicked reactions may Morph to agility, making Maledict even more efficient than intended.
* Adaptive Strike (Strength) can interrupt Death Ward at a decent range.

* Quill Spray and Bristleback harass Luna more efficiently than she does with Lucent Beam.
* Bristleback withstands Luna’s nukes, and gives lots of damage in return.
* Viscous Nasal Goo and Warpath are enough to outrun a speedy Luna.
* Bristleback tends to be a frequent carrier of Crimson Guard, which is good protection from bouncing glaives.
Additional:
* Multiple instances of damage from Eclipse will trigger Bristleback's passive repeatedly in a short time, dealing tremendous damage to Luna and her teammates.
* Luna's damage burst may be high, but it will not be enough for her to take down Bristleback.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Devourer.

* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa.

* Without Dust of Appearance or Sentry Wards, Riki is able to silence Witch Doctor with Smoke Screen, and is likely to build a Diffusal Blade, leaving Witch Doctor without mana to cast Voodoo Restoration, as well as Skull Basher to interrupt Death Ward.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Devourer.

* Heroes that create illusions (such as Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress and the aforementioned Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).

* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.

* Escape-type carries: Slark, Storm Spirit, Weaver.

* Heroes that rely on base damage: Luna, Phantom Lancer are easily countered with Anchor Smash.

* Kraken Shell dispels the stun from Paralyzing Cask. However, it does not dispel the damage from Maledict.
* Once Witch Doctor first uses his Death Ward in team fights, Tidehunter can simply cancel it with Ravage, turning the tables against him, especially if Witch Doctor does not have a Black King Bar.
* As a precaution, let Tidehunter use Ravage first before channeling Death Ward to turn a team fight in your favor.

* Death Ward's first target (before it bounces) can evade it, therefore Windranger and Phantom Assassin are poor choices to use it on.
* However, once the first hit landed, the bounces can no longer miss. Don't forget to manually aim for a target with no evasion !

* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.

* Escape-type carries: Slark, Storm Spirit, Weaver.

* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.

* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.

* Heroes like Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.

* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Drow Ranger, Luna, Sniper, Troll Warlord, Weaver, Clinkz.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Devourer.

* Heroes that create illusions (such as Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress and the aforementioned Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).

* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor

* All assassin-type carries in a one against one situation: Meepo, Phantom Assassin, Riki, Ursa.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* Heroes with long channeling abilities like Witch Doctor are easy targets for Kunkka to interrupt in team fights.

* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Devourer.

* Shadow Dance prevents Luna from damaging Slark, and together with Shadow Blade he can kite her or escape.
* Luna has no way to escape from Pounce's leash.
Additional:
* Luna's lack of mobility and escape abilities makes her easily gankable by Slark.
* Shadow Dance will avoid all the damage from Eclipse.
* For the same reasons, Slark is a good ally for Luna when they are in the same team.

* A couple of long-range heroes with excellent laning like Mirana, Lina, Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.

* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.

* Arc Warden's Magnetic Field dodges all damage from Death Ward. Should he choose to buy a Necronomicon, they are quite effective to absorb some shots from your cask, and attack you during Death Ward.

* Heroes that create illusions (such as Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress and the aforementioned Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).

* 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 Devourer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* 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.

* Heroes that create illusions (such as Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress and the aforementioned Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).

* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
