Patch Patch 1.8.92 2024-06-19
As one of Cecilion's core equipment, the revamp of Clock of Destiny slighty reduced his damage but greatly increased his survivability. We recognize this change. This time, we reduced the foreswing of Skill 2 to increase its hit rate.

Removed the foreswing of Skill 2 (delay time unchanged).

Path Damage Bonus from Max Mana: 5% → 7%
End Damage Bonus from Max Mana: 10% → 14%
Patch Patch 1.7.08 2022-08-09
For a late-game mage, Cecilion's been casting quite a shadow upon the battlefield early on with his high damage, so we're drawing some of his Bat Impact back into the cave.
Skill 1 -  Bat Impact
Base Damage: 100-250 → 85-235
Patch Patch 1.6.84 2022-05-23
Cecilion's been overshadowing other mages with his superb damage and sustainability, so we're cutting away some of his innate defensive power.

Base Physical Defense: 20 → 18
Patch Patch 1.6.42 2021-12-21
Scaling speed slightly increased.

Removed the slow effect.

This is the first time we design a hero couple which has a special interactive skill. Don't forget to try them together with your friends!
He is the lover of the Shadow of Twilight, Carmilla.
Passive -  Overflowing
Cecilion will increase his max mana each time his skill hits an enemy target. Cecilion's skill damage scales with his max mana.
Skill 1 -  Bat Impact
Cecilion orders a giant bat to dive in a designated direction, dealing damage to enemies on the path. The giant bat will stay at its destination and launch another attack, dealing the same damage to them again. After casting, Cecilion increases his Movement Speed. In several seconds, every time Cecilion casts this skill, the mana cost will be doubled.
Skill 2 -  Sanguine Claws
Cecilion summons a pair of claws in a designated position. The claws will run into each other afterwards, dealing damage to enemies on the path, pulling them to where the claws meet and immobilizing them.
Ultimate -  Bats Feast
Cecilion awakens his Blood Demon power, increasing his Movement Speed. Meanwhile, he releases Blood Demon Power, dealing damage to enemies around him and slowing them. Each time the Power hits a target, Cecilion restores a certain number of HP.
Special Skill -  Moonlit Waltz
When Carmilla is nearby, Cecilion can transform her into a Vermeil Shadow attaching to him and providing shield. Carmilla can select a target place and land there. This skill can be unlocked only when Carmilla is in the battlefield with Cecilion.
