What Lee Sin Rewards

Blind Monk · printed ability

“1 Energy,: Buff a friendly unit. (If it doesn't have a buff, it gets a +1 Might buff.)”

Lee Sin asks you to care about combat math; the fun is setting up fights where your units survive because the Legend ability changes the numbers.

How it plays

The Game Plan

Lee Sin is a simple but precise buff engine. His ability turns spare energy into a persistent buff marker that feeds buff-matters cards and grows the unit that must survive the next battlefield fight.

Strengths

  • Repeatable buff access
  • Good protected-threat plan
  • Works well with Calm/Body combat tricks

Watch Outs

  • Ability is slow at one buff per exhaust
  • Needs a unit worth investing in
  • Can fall behind to wide boards

Turn by Turn

  1. 1Early: choose the unit that will carry the first buff instead of spreading resources randomly.
  2. 2Midgame: protect the buffed unit through Showdowns so the energy spent keeps mattering.
  3. 3Late: stack buffs and protection only where they convert into Holds or final conquest points.

New to this Legend? Pick Lee Sin if you want a clean buff deck built around one important fighter staying alive.

Keep

  • Keep the Calm/Body core of buffs, protection, and unit combat.
  • Keep efficient units that make combat tricks matter.

Upgrade First

  • Add more protection for your best battlefield unit.
  • Upgrade cards that do not help you win or survive Showdowns.

Try Next

  • Try extra buff sources if you want a taller threat plan.
  • Tune toward more Body if you need raw Might, or more Calm if you need staying power.
