Howling Abyss rules
Prepare for one shared lane
ARAM removes the normal Rift role map. Build around the champion, the five-player team and the next fight instead.

You cannot Recall to buy. Plan components before leaving the shop and use each death timer deliberately.
A relic heals nearby allies after a short delay. Signal it and avoid taking the trigger when a lower-health teammate needs the area.
Minions create structure pressure and safer space. Clearing first can be more useful than forcing another low-health engage.

ARAM rewards reliable access to clustered fights. Mark helps a melee front liner enter; Flash preserves a separate escape or reposition.
Resolve
Precision
Mark and Clarity are mode-specific choices. Do not copy this pair onto a Summoner's Rift page.
Choose the second spell around access, survival and team resources rather than treating every ARAM champion as a diver.
Matchup notes
What changes when Vex is opposite you?
Compare reliable reach and repeatable value
Track which champion can apply damage, control or protection without crossing the enemy team's safe space. ARAM does not turn this kit comparison into a lane-counter claim.
Team context firstRerolls, allied range, engage and protection can matter more than either champion in isolation.
Use the route you prepared
Use the champion-specific ARAM build as a starting reference, then check the current Recommended shop, your five-player composition and the next available death shop.
Lee Sin reminders
- Use Sonic Wave before Dragon's Rage so you can chase the target with Resonating Strike.
- Take advantage of Flurry by weaving in basic attacks between spell casts - this maximizes damage output and minimizes Energy loss.
- Self-casting Safeguard and using Iron Will are powerful tools for killing neutral monsters (in the jungle).
Static alternatives

Lee Sin
- PFlurry
After Lee Sin uses an ability, his next 2 basic attacks gain Attack Speed and return Energy.
- QSonic Wave / Resonating Strike
Sonic Wave: Lee Sin projects a discordant wave of sound to locate his enemies, dealing physical damage to the first enemy it encounters. If Sonic Wave hits, Lee Sin can cast Resonating Strike for the next 3 seconds. Resonating Strike: Lee Sin dashes to the enemy hit by Sonic Wave, dealing physical damage based on the target's missing Health.
Cooldown (s) 10/9/8/7/6 · Cost 50 · Listed range (units) 1100 - WSafeguard / Iron Will
Safeguard: Lee Sin rushes to target ally, shielding himself from damage. If the ally is a champion, they are also shielded. After using Safeguard, Lee Sin can cast Iron Will. Iron Will: Lee Sin's intense training allows him to thrive in battle. Lee Sin gains Omnivamp.
Cooldown (s) 7 · Cost 50 · Listed range (units) 700 - ETempest / Cripple
Tempest: Lee Sin smashes the ground, sending out a shockwave that deals magic damage and reveals enemy units hit. If Tempest hits an enemy, Lee Sin can cast cripple.

Cooldown (s) 8 · Cost 50 · Listed range (units) 450 - RDragon's Rage
Lee Sin performs a powerful roundhouse kick launching his target back, dealing physical damage to the target and any enemies they collide with. Enemies the target collides with are knocked into the air for a short duration. This technique was taught to him by Jesse Perring, although Lee Sin does not kick players off the map.

Adapt the plan
What to do when the game changes
Judge the whole lane or map state, not only personal kills. Choose the situation closest to the current game.
Protect the lead while the lane stays shared
Clear together and keep enough health to use the next structure window.
Use brushes and the available healing safely; there are no side lanes to abandon.
Keep useful allies in reach and avoid giving away shutdowns through an isolated chase.
Trade around health, range and the next wave
Let the team clear without spending every important cooldown at once.
Track the shared lane, brush control and available relics rather than looking for a Rift rotation.
Use the champion's reliable range, protection or control before forcing a low-percentage engage.
Use structure space and coordinated clears
Clear from safety and avoid dying before the next minion wave reaches the structure.
Wait for teammates to respawn instead of walking into the shared lane alone.
Punish overextension and preserve the cooldown that can stop the first enemy commitment.
Shared-lane plan
Lee Sin on Howling Abyss
Read health, range, wave position and respawn timing together. ARAM has no side-lane rotation, neutral-objective setup or normal ward-control loop.
Clear or escort the wave, check which allies are alive and preserve enough health to use the champion's reliable range, protection or engage.
Use the nearest safe target and the team's reachable follow-up. Do not cross the whole enemy formation for a single low-health champion.
Push with surviving minions, take the safe structure damage available and reset only through a real death rather than donating one alone.
Keep preparing
