Unreviewed route

No reviewed Sion Bot build

Sion is normally played Top and does not currently have a reviewed Bot route. Bot usually needs dependable duo-lane scaling and sustained damage with shared early pressure. Treat this as a deliberate experiment, not a standard recommendation.

A different lane's items are not relabelled as correct. Role income, map access and starting rules can change the whole purchase order.

A melee Bot route must survive ranged access before committing. Conqueror supports the longer entry while Barrier protects the close-range damage window.

Coordinate the Support

Avoid duplicating the same defensive spell without a reason. Barrier protects the user; Heal can protect both nearby lane partners.

Cleanse is specific

Choose Cleanse only when removable crowd control is the lane or fight problem and you can use it reliably.

Kit reference

Sion abilities

Ability names, descriptions and numeric fields come from Riot Data Dragon. Practical reads are independently written; the current in-game tooltip remains authoritative.

P

Glory in Death

What it doesAfter being killed, Sion will temporarily reanimate with rapidly decaying Health. His attacks become very rapid, heal him, and deal bonus damage based on his target's maximum Health.

Practical readGlory in Death is an automatic part of the kit involving protection or sustain and damage. Track when its condition is active instead of treating every fight the same way.

Maximum-health interaction

This effect references a maximum-health value. Check whether the current tooltip uses the caster's or the target's health before comparing damage or protection.

Q
Q ability

Decimating Smash

What it doesSion charges a powerful swing in an area in front of himself that will deal damage to enemies when released. If he charges for enough time, enemies hit by the swing will also be knocked up and stunned.

Practical readDecimating Smash contributes damage. Its value changes with cooldown, range and target access; recognise the setup before moving into its effective area.

Cooldown10/9/8/7/6 secCost45Listed range10000 units

This cast has a wind-up, charge or channel. Movement, interruption or a changing target state can matter before the effect completes.

Soul Furnace

What it doesSion shields himself and can reactivate after 3 seconds to deal Magic Damage to enemies nearby. When Sion kills enemies, he passively gains maximum Health.

Practical readSoul Furnace contributes damage. Its value changes with cooldown, range and target access; recognise the setup before moving into its effective area.

Maximum-health interaction

This effect references a maximum-health value. Check whether the current tooltip uses the caster's or the target's health before comparing damage or protection.

Protection

The protection or sustain is part of the cast's value. Compare its timing with incoming damage rather than reading only the offensive effect.

E
E ability

Roar of the Slayer

What it doesSion fires a short range shockwave that damages and slows and reduces the Armor of the first enemy hit. If the shockwave hits a minion or monster, it will be knocked back, damaging, slowing, and reducing the Armor of all enemies that it passes through.

Practical readRoar of the Slayer is a ranged cast involving a slowing effect and damage. Respect its line or target area, and avoid spending it when the opponent can simply step away before the important exchange.

Cooldown12/11/10/9/8 secCost35/40/45/50/55Listed range800 units
First target

The first valid unit in the path receives or stops the effect, so minions, monsters or champions can change the result where the tooltip allows them.

Unstoppable Onslaught

What it doesSion charges in a direction, ramping up speed over time. He can steer his charge slightly with the mouse cursor location. When he collides with an enemy he deals damage and knocks them up based on the distance he has charged.

Practical readUnstoppable Onslaught contributes movement or repositioning and damage. Its value changes with cooldown, range and target access; recognise the setup before moving into its effective area.

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.

Even plan

Prioritise farm, spacing and coordination with Support

1
Lane

Match the opposing carry's income and trade when both lane partners can participate.

2
Map play

Finish the wave before rotating unless the fight is immediate and clearly reachable.

3
Fights

Stand behind allied control and build damage on reachable targets before stepping toward the back line.

Pings, movement and objectives

Sion Bot map plan

Protect income and coordinate with Support. Your movement should follow the wave, while your pings make target choice and danger clear before the fight begins.

Ahead

Carry the lead into the next safe fight

Ping
Use Target on the reachable opponent, Danger when Support or Jungle is too far away, and On My Way after the wave is secured.
Farm or rotate
Finish the wave, recall on the item timing and rotate with protection. Do not cross river alone to save a few seconds.
Objective
Attack from the safe side of the objective and keep damaging the nearest reachable threat. Preserving the shutdown matters more than chasing.
Even

Build the item timing and move together

Ping
Use Target to align with Support, Enemy Missing when either Bot opponent leaves and Danger if an engage begins outside your safe range.
Farm or rotate
Rotate after the wave or when the objective fight is immediate and reachable. Communicate if staying for the wave is the safer call.
Objective
Enter behind vision and allied control. Keep a route away from the enemy engage before starting sustained damage.
Behind

Shorten exposure and recover guaranteed gold

Ping
Use Retreat before Support or Jungle forces a fight you cannot damage, and Enemy Missing as soon as the winning Bot lane leaves.
Farm or rotate
Avoid being first into river. Move with Support after the safe wave, or trade an unsafe objective for protected farm.
Objective
Stand beside peel and attack whoever enters safe range. Do not cross enemy control to reach the opposing carry.
Objective setup

Four calls, in order

Pings create a shared plan; they do not replace checking waves, vision and who can move.

  1. 1
    Secure the wave

    Finish safe farm and communicate the recall or move before the objective setup begins.

  2. 2
    Enter protected

    Walk with Support or another ally and choose the side where enemy engage cannot reach you first.

  3. 3
    Set attack space

    Keep an exit route and identify the nearest target you can damage without crossing enemy control.

  4. 4
    Stay alive

    Continue useful damage without chasing away from the objective or donating a shutdown.

Later objectives: Repeat the same process around later major objectives: handle nearby income, communicate the route, enter through vision and agree on the fight before committing.
