Hero Information

Sima Yi

Class: Mage, Assassin
Chinese Name: 司马懿

Sima Yi is like a walking shadow, shrouded in darkness from head to toe, always waiting for the perfect opportunity to strike. Originating from an aristocratic family that cold-bloodedly sacrificed him in their thirst for power, he briefly enjoyed a peaceful life as a student at the Jixia Academy before embarking on a dark path of vengeance. Manipulating shadow energy to manifest a giant scythe, he stands ready to reap all enemies who dare cross his path.

Skills and Abilities

Silent Words

(Passive)

Sima Yi gains vision of enemy spellcasters within a 2000 range when they cast skills and restores 5 Energy per cast.

Sima Yi starts with a base Energy pool of 80 (gaining +3 Energy per level). Scoring a kill or assist permanently increases his maximum Energy by 10 points (up to 200 max Energy). Eliminating monsters or enemy heroes immediately restores 10 Energy.

Casting any skill activates Shadow Fang for 4 seconds, granting 30 bonus Movement Speed and transforming basic attacks into dark scythe strikes that deal 250–390 (+40% Magic Attack) Magic Damage per hit. The enhanced basic attack right after skill activation blinks Sima Yi behind the target, dealing 330–660 (+70% Magic Attack) Magic Damage.

Shadow Bite

Cooldown: 10s

Sima Yi becomes immune to crowd control effects and releases a rapid shadow spirit under his control for up to 2 seconds.

Enemies passed through by the shadow spirit take 100/120/140/160/180/200 (+20% Magic Attack) Magic Damage. Minions and jungle monsters take an additional 200/220/240/260/280/300 (+20% Magic Attack) Magic Damage.

Upon casting a basic attack or when the spirit's duration expires, Sima Yi's physical body immediately teleports to the spirit's location, dealing 100 (+20% Magic Attack) Magic Damage to enemies along the path and slowing them by 50% for 1 second.

Desolate Realm

Cooldown: 6s

Sima Yi unleashes his spiritual power to suppress the surrounding field, dealing 300/340/380/420/460/500 (+30% Magic Attack) Magic Damage and silencing nearby enemies for 1 second.

If Sima Yi remains inside the suppressed zone after 2 seconds, he restores 25/30/35/40/45/50 Energy.

Passive: When taking Magic Damage, 50% of the incoming Magic Damage is converted into HP over the next 2 seconds.

Death's Coming

Cooldown: 35/30/25s

Sima Yi steps backward briefly to channel shadow energy before dashing forward across a massive distance to the target location, dealing 600/800/1000 (+100% Magic Attack) Magic Damage to the landing area and 50% damage to targets along his path.

Gameplay Tips and Easy Combos

Maximize Max Energy Early: Active participation in early skirmishes is crucial. Kills and assists permanently increase Sima Yi's maximum Energy pool, allowing him to unlock his full combo potential early in the match.
Predict Ultimate Placement: Sima Yi's Ultimate (Death's Coming) has a brief wind-up animation. Always anticipate enemy movement paths to land the impact accurately or catch fleeing targets.
Flank and Target Enemy Carries: While Sima Yi possesses unmatched long-range dive capabilities, his squishy assassin nature makes initiating teamfights risky. Always wait for your team's tanks or frontline fighters to initiate, then swoop in to eliminate high-value squishy targets in the backline.
