Kaecillus

Abillities
Master Combatant : Kaecillus was a very capable martial artist,both Armed and Hand to Hand Combat. He was noted to be among the finest warriors in the Master of the Mystic Arts and in a flashback,he was seen easily beating 5 opponents at once. The leader of the Zealots,Kaecillus was the strongest fighter out of the group,managing to hold his own against the Ancient One herself,altough only after he was empowered,but he was incapable of defeating or even matching her on his own and needed a surprise attack and sacrifice of his minions to kill her. He also managed to outmatch Stephen Strange in their duel on New York Sanctum,only being prevented from killing him due to the Cloak of Levitation saving Strange. While using the altered surroundings of the repairing Hong Kong allowed Strange to compete with him,Kaecillus still proved to be too strong,managing to equal and even at times gain the upper hand over him,forcing Strange to bargain with Dormammu to defeat Kaecillus.

Powers
Dark Dimensional Magic Manipulation : Kaecillus was able to perform the spell to tap into the powers of the Dark Dimension alongside Lucian and 3 other Zealots,gaining greater power and allowing him to manipulate Space and Reality in both the Mirror Dimension and Earth and craft Space Shards. He also gained enhanced momentum that allowed him to easily send humans flying with his attacks and also became able to totally disregard gravity,able to run on vertical surfaces comfortably. Being connected to a Dimension beyond Time,Kaecillus was able to substract himself from the effects of the power of the Time Stone.

Arcene Lore/Magical Mastery : Noted to be one of the most brilliant students of the Ancient One,Kaecillus was extremely talented and skilled in the Mystic Arts,being among the most powerful member of the order before betraying it and becoming the leader and strongest of the Zealots. His skills as a Sorcerer was great enough that the Ancient One considered him as a potential candidate for the title of Sorcerer Supreme. Once he was empowered by tapping into the power of the Dark Dimension,Kaecillus proved powerful and skilled enough to hold his own against the Sorcerer Supreme herself.
