Lee Sin
View on Wiki
Poor (2/10)
High Investment Required
Epic Relics
Lee Sin is widely considered one of the weakest champions in the game due to his slow, mana-hungry, and card-hungry playstyle. His star powers are often described as clumsy, and his units lack inherent durability. However, he maintains a highly effective niche as a top-tier choice for specific Monthly Challenges, particularly those that start with 10 mana.
The Perfect Kick
Provides consistent, low-cost spell generation to accelerate Lee Sin's level-up condition and grant essential keywords, mitigating his inherent mana hunger.
Serves as the core engine for his late-game win condition, doubling powerful spells once the 6-mana threshold is reached.
Grants the strictly necessary Overwhelm keyword to push damage and overcome chump blockers.
Strategy
This build focuses on surviving the early game while using Perfect Hex Core to stack keywords and advance Lee Sin's demanding level-up condition. The Troll King's Crusher provides the essential Overwhelm keyword to ensure his kick damage reaches the Nexus and isn't wasted on chump blockers.
Chemtech Duplicator serves as the core engine for his late-game win condition. Once the 6-mana threshold is reached, it doubles powerful spells, allowing Lee Sin to scale rapidly and finish the game.
10-Mana Speedrunner
Creates a Homecoming to act as interaction and disruption, while scaling Lee Sin's power when units are recalled.
Provides Fated and Augment to scale his stats rapidly, while granting Overwhelm once Empowered 10 is reached to ensure Nexus damage.- Immediately active on 10-mana nodes, doubling all spells cast to guarantee a First Turn Kill (FTK).
Strategy
This highly specialized build is designed exclusively for Monthly Challenges or mutators that grant 10 starting mana. Because Chemtech Duplicator is active immediately, you can instantly double your spells to buff Lee Sin to lethal ranges.
Chosen by the Stars provides the necessary Overwhelm keyword once his stats are buffed, allowing for a reliable First Turn Kill (FTK). Essence Theft creates a Homecoming to act as interaction and disruption while scaling Lee Sin's power.
Starforged Impact Combo
Enables a massive 30 Impact damage combo when paired with Overwhelm.- Provides the Overwhelm keyword required to maximize the Starforged Gauntlets combo.
- Provides the consistent spell generation needed to reach his level-up state.
Strategy
This build enables a massive damage combo utilizing Starforged Gauntlets. When combined with Overwhelm from The Troll King's Crusher, Lee Sin can deal 30 Impact damage in a single turn after some preparation.
Ensure Lee Sin levels up and gains Overwhelm to maximize the damage from Starforged Gauntlets, effectively providing a one-shot victory. Perfect Hex Core provides the consistent spell generation needed to reach this state.
Other Relic Options
Potentially effective for its summon and attack damage effect, though Lee Sin often lacks the available relic slots to accommodate it.
Provides immediate spell generation upon summoning, though it is generally less preferred than Perfect Hex Core due to Lee Sin's slower, combo-oriented playstyle.
Constellation
Lee Sin is widely considered one of the weakest champions, requiring significant investment (Level 30 and two Epic relics) to perform adequately. His core gameplay loop is incredibly mana-hungry and card-hungry. His 3-star powers are clumsy because his temporary buffs are limited to a single unit, restricting his board impact. Furthermore, his generated spell, Resonating Strike, does not receive a cost discount, making his spell usage less efficient compared to newer champions. His 2-star ability is also considered weak and in need of a buff.

Gameplay Tips
- Monthly Challenge Specialist
While Lee Sin struggles in standard high-difficulty adventures (beyond 4.5 stars), he is a top-tier choice for Monthly Challenges. He is exceptionally effective in speedruns (sub 2 hours) or against mutators that start players with 10 mana, as this completely bypasses his slow setup and mana starvation.
- The Overwhelm Requirement
Lee Sin strictly needs the Overwhelm keyword to be an effective finisher. Without it, he is easily chump blocked before leveling up, and the massive damage from his Dragon Kick will strike the Nexus, but the subsequent regular attack will be absorbed by the blocker. Always secure Overwhelm through relics like The Troll King's Crusher.
- Manage Mana Carefully
Lee Sin is extremely mana-starved and requires significant resources to play units and spells in the same round. He is not effective if he cannot play two spells per round, making consistent spell generation and mana management critical to his success.
- Leverage Event Synergies
Lee Sin performs particularly well in the Fizz adventure and the Titan event. The Titan event is highly favorable as it helps bring Chemtech Duplicator online very quickly, accelerating his win condition.
