Scaling mage whose skill damage grows with his Max Mana pool
Cecilion converts every point of Max Mana into skill damage through Overflowing, so mage items that would normally just extend his mana pool directly raise his ceiling. Bat Impact restores mana on every hit, letting him poke almost for free, while Bats Feast turns a full-HP backline into a shredded one in a single six-second channel once he hits his damage-scaling core items.
Bat Impact's cost escalates by 1.8x with every repeated cast within 6 seconds, so managing mana between poke and the ultimate's channel window takes real resource discipline.
Max Bat Impact first for poke and mana sustain, level Sanguine Claws for the pull but don't max it early, and take Bats Feast at every level it's available.
Cecilion increases his Max Mana by 10 and restores the same amount of Mana his skill hits an enemy target. Cooldown: 1 second. Cecilion has higher Max Mana and Mana Regen, and his skill damage scales with his Max Mana.
Always active — no cooldown
Cecilion orders a giant bat to dive in a designated direction, dealing 100–250 (+80% Total Magic Power) (+5% Total Mana) Magic Damage to enemies on the path. The giant bat will stay at its destination and launch another attack, dealing 200–500 (+160% Total Magic Power) (+10% Total Mana) Magic Damage to enemies and triggering Overflowing extra 1 time. In 6 seconds, every time Cecilion casts this skill, the mana cost will be increased by 1.8 time(s) (capped at 4 times).
Our source cuts this description off mid-sentence — the rest is not shown.
Cecilion summons a pair of claws in a designated location. After a short delay, the claws will move toward each other and pull enemies along the way to the center, dealing 200–300 (+45% Total Magic Power) (+1.2% Total Mana) Magic Damage and immobilizing them for 1 second.
Cecilion unleashes Blood Demon power for 6 seconds, increasing his Movement Speed by 60% (decaying rapidly over 1.5 seconds) and gaining immunity to slow effects. Meanwhile, he shoots 40 bolts of blood energy at the enemies nearby, each dealing 35–45 (+8% Total Magic Power) (+0.3% Total Mana) Magic Damage and slowing them by 3% (up to 30%) for 1 second. Hitting an enemy heals him for 10 and 1% of his lost HP.

The heroes that make this matchup hard, and the mechanic that does it.
HanzoAssassinHardAs Hanekage he charges in through terrain from off-screen while his real body sits somewhere else invincible, punishing Cecilion's zero mobility the moment he's spotted out of position.
HayabusaAssassinHardNinjutsu: Quad Shadow's dash and phantoms close distance instantly, and Ougi: Shadow Kill bursts Cecilion down before Bats Feast can even start channeling.
YinFighter · AssassinHardMy Turn pulls Cecilion into a domain where no ally can reach him, and Lieh's enhanced skills kill him there before he can retreat to safe range.
AamonAssassinHardEvery shard he lands puts him back into Camouflage, so he closes untargetable and deletes Cecilion's low-mobility frame before Overflowing's damage scaling matters.
HarleyAssassin · MageHardHis blink combo closes distance instantly and one-shots immobile backline mages like Cecilion before they can react.
GlooTankSoftHe sticks to Cecilion regardless of kiting attempts, closing the range advantage that Bat Impact's poke depends on.
IxiaMarksmanSoftFull Barrage sprays a wide fan at up to six targets while Siphon Starlium heals her off the damage, so she out-trades Cecilion in lane and punishes him for standing still to channel Bats Feast.
NovariaMageSoftHer Astral Spheres slow everything near them and Astral Echo enlarges his hitbox while revealing him, poking Cecilion down and forcing him off position before he can safely channel his ultimate.
LunoxMageSoftHer adaptive Order and Chaos forms give her either the burst or the CC needed to punish Cecilion's total lack of an escape tool.
AldousFighterSoftContract: Soul Steal's stacked attack scales off kills rather than items, so it threatens a one-shot regardless of what Cecilion builds, and Contract: Chase Fate closes the gap he relies on for safety.Winter CrownThe damage-immune window lets a target survive Bats Feast's channel burst entirely.
Athena's ShieldThe flat magic damage reduction blunts a single Bats Feast rotation, especially in shorter fights.

BrodyMarksmanHe cleans up targets that Cecilion has already poked low with Bat Impact before they can retreat.Prioritize Max Mana items early — Overflowing means mana pool is a direct damage stat for Cecilion, not just a resource
Land Sanguine Claws before committing Bats Feast, so the pull immobilizes targets in place for the full channel duration
Poke freely with Bat Impact in lane — Overflowing's mana refund on hit means it rarely runs him dry against a target he's hitting
Position at max range before starting Bats Feast, since its slow immunity protects mobility but not against hard CC landing mid-channel
Reasonably approachable in lane since his poke is simple, but he's totally reliant on positioning and teammates for safety since he has no dash or escape of any kind.
Arcane Boots into Clock of Destiny, Glowing Wand, and Holy Crystal maximizes Overflowing's Max Mana scaling into raw burst. Swap in Divine Glaive against a stacked Magic Defense frontline.
Any hard-diving assassin — Hayabusa, Yin, Aamon, Harley — closes distance instantly and kills him before Bats Feast can channel. He has zero personal mobility to answer with.
Overflowing scales his skill damage directly off Max Mana, which only grows large after several core items. Farm safely early and he becomes one of the highest-damage mages once his mana pool scales up.
