Phoenix slows enemies with Fire Spirits and locks them with Supernova while Stone Gaze activates. Sun Ray heals Medusa while she tanks the front line. Their AoE presence makes it hard to fight into them. They scale well into late game together with strong teamfight control.

Medusa's Mana Shield is essentially her HP bar, which makes her the perfect counter to Ice Blast as it does not affect mana regeneration in any way, completely rendering the impact of the spell to only a fraction of it. Manta and Butterly are staple items for Medusa, with which she can Dispel Cold Feet and Evade Chilling Touch hits.

Mana Shield does not take into account any Armor or Magic Resistance, making it the perfect counter to Doom's Pure Damage. Cold Blooded (Aghanim's Shard Upgrade) when combined with Aghanim's Scepeter allows Dusa to stun Doom upon casting Doom and naturally create distance. Doom lacks Mana Burn and the Attack Speed to justify a Diffusal/Disperser and struggles greatly to get trough Dusa's Manapool.

Medusa’s Mana Shield absorbs Bloodseeker’s burst damage from Thirst and Rupture. She can stand still during Rupture and deal damage safely with Split Shot. In late game, she becomes too tanky for Bloodseeker to finish off. Bloodseeker’s lack of scaling struggles against Medusa’s farm pace.

Leshrac’s magic damage becomes less effective against Medusa’s massive mana pool. Mana Shield absorbs Pulse Nova and Edict chip damage easily. Medusa can outlast Leshrac in drawn-out fights and kill him after BKB ends. Her ranged attacks punish Leshrac’s close-range playstyle.

Undying is strong early, but his impact falls off as Medusa scales. Medusa easily kills Tombstone with Split Shot without committing. She shrugs off Decay stacks with mana tanking. Undying lacks the burst or control to ever threaten her late game dominance.

Medusa clears Beastmaster’s summons with Split Shot and builds stats to avoid Roar burst. Hawk vision and summons become less valuable against her AoE pressure. Beastmaster’s physical push is stalled by Medusa’s wave clear. In late game, she outscales Beastmaster easily.

Witch Doctor’s Death Ward becomes ineffective when Medusa activates Mana Shield. He lacks burst damage and can’t stop Medusa’s scaling. Maledict fails to finish her off through sustain and stats. Medusa kills him quickly with ranged damage during fights.

Elder Titan’s armor reduction is partially countered by Medusa’s tankiness. She zones him out of fights and kills Spirit easily. His magic damage does little to her mana pool. Medusa can kite him while he sets up for Echo Stomp or Earth Splitter.

Medusa builds Manta or BKB to avoid Black Hole setups. She farms faster and scales better into ultra-late game than Enigma. Even if caught, Mana Shield can delay her death long enough for teammates to respond. She can also clear Eidolons and push against him.

Queen of Pain lacks the sustained damage to break Medusa’s mana pool. Her blink harassment fails once Medusa has items. Sonic Wave doesn’t deal lethal damage due to Mana Shield. Medusa forces longer fights where QOP gets outdamaged and zoned.

Techies' mines and magical burst are ineffective against Medusa’s passive damage soaking. She can tank proximity mines and still fight. Blast Off initiation is absorbed and punished. Medusa’s slow siege style denies Techies time to set up traps.

Medusa’s Split Shot clears CK’s illusions quickly before they can overwhelm her. Mana Shield stops most of CK’s burst from Chaos Strike crits. CK struggles to kill her even with full combo. Medusa dominates illusion heroes in teamfights.

Simply put by the time Medusa is ready to fight Alchemist is ready to end the game. Her inability to pressure early or scale quickly when paired against Alch's farming potential often result's in games where she has half an inventory versus a maxed out Alch. Chemical Rage and Berserk Potion dispel Gorgon's Grasp.

Mana Break is amazing at shredding trough Medusa's mana pool and turning her core defensive mechanic Mana Shield against her with a huge Mana Void follow up . Manta is a staple item for AM that provides him with dispel for Gorgon's Grasp root and Counter Spell can block/reflect Mystic Snake.

Wall of Replica and Normal Punch (Aghanim's Scepter Upgrade) can create multiple Illusions of Medusa to do devastating amounts of damage to her own team as she tends to build heavy stat items to improve her own Manta Illusions' damage and durability. The Illusions DS creates inherit both Mana Shield and Split Shot if it was active at the moment of creating the Illusion. Surge is amazing at disengaging from Stone Gaze or closing the gap on Dusa.

Nyx burns Medusa’s mana with Mana Burn and stuns her with Spiked Carapace off Split Shot. Vendetta bursts her before she can react. She triggers his spells unintentionally with constant attacks. Nyx repeatedly harasses and disables her during crucial fights.

Slark dodges Split Shot and Stone Gaze with Shadow Dance and pounces out of danger. He builds up Essence Shift during drawn-out fights. Medusa can’t hit him reliably in fog or darkness. She struggles to lock him down or match his agility scaling.

Centaur absorbs her attacks with Retaliate and initiates with Hoof Stomp. Stampede helps his team disengage from Stone Gaze. Medusa’s slow mobility becomes a liability against his high-tempo play. He survives her damage and enables his allies to burst her.

Alchemist farms much faster than Medusa and applies pressure earlier. His BKB timing allows him to ignore Stone Gaze. Acid Spray and Unstable Concoction burst Medusa before she’s fully online. He snowballs into late game with more map control.

Pangolier’s Rolling Thunder disables Medusa during her Stone Gaze and ruins positioning. Diffusal Blade drains her mana quickly and forces retreat. His mobility allows him to avoid Split Shot and kite her. Pango controls teamfights where she needs to stand ground.

Monkey King builds Diffusal Blade and stays in Wukong’s Command to drain Medusa’s mana. She can’t escape the arena without items like Force Staff. His high physical DPS overwhelms her early before she scales. He jumps on top of her and avoids most of her damage.

Shadow Demon disrupts Medusa during her Stone Gaze and makes illusions of her. These illusions deal high damage and drain her mana with Split Shot. Disruption saves allies from Life Drain and Mystic Snake. He stalls fights long enough to counter her momentum.

Sniper outranges Medusa and chips her down safely from distance. She struggles to reach him through his mobility and slows. Sniper doesn’t rely on mana, so Stone Gaze has minimal impact. He scales better with attack range and pure damage items.
