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.

01
Start together

Review rerolls and the shared bench, then leave with an opening that fits this champion and the team around it.

02
Shop while dead

You cannot Recall to buy. Plan components before leaving the shop and use each death timer deliberately.

03
Share health relics

A relic heals nearby allies after a short delay. Signal it and avoid taking the trigger when a lower-health teammate needs the area.

04
Fight with the wave

Minions create structure pressure and safer space. Clearing first can be more useful than forcing another low-health engage.

ARAM · Howling Abyss

ARAM marksman reference

Compare the opening with Riot's ARAM Recommended shop before leaving base. After that, purchases happen only while dead; the six usable inventory slots do not increase.

Mark and Clarity are mode-specific choices. Do not copy this pair onto a Summoner's Rift page.

Protect the next fight

Choose the second spell around access, survival and team resources rather than treating every ARAM champion as a diver.

Static alternatives

Compare the problem before changing the plan

These choices are not selected from live scores. Use one only after you identify the stated match problem yourself.

Only when enemy healing is deciding fights

Oblivion Orb

Oblivion Orb supplies healing reduction without committing to a completed Morellonomicon. Skip both when healing is not the problem or an ally already covers your target reliably. Healing reduction does not reduce shields.

Conditional component, not a core item. Complete Morellonomicon only when its stats and slot efficiency justify delaying another purchase.
They burst me

Zhonya's Hourglass

Zhonya's stasis can absorb a committed dive or lethal burst window.

One spell stops me

Banshee's Veil

Banshee's spell shield can protect the first important cast against you.

They stack magic resist

Void Staff

Void Staff becomes valuable when the target has bought meaningful magic resistance.

Situational AP purchase

When should you buy anti-heal?

Buy healing reduction when enemy healing or regeneration is deciding fights and you can keep damaging the relevant target. Grievous Wounds reduces healing; it does not reduce shields, magic damage or crowd control.

Start with the component

Oblivion Orb can provide healing reduction without immediately paying for a completed Morellonomicon. Fit the component around your core damage, mana and survival needs; check the current queue's item tooltip.

Finish when it fits the fight

Complete Morellonomicon when its stats and slot efficiency suit your build. Do not treat it as a mandatory first item just because your champion deals magic damage.

Coordinate coverage

Multiple Grievous Wounds sources do not add their percentages together. Another reliable applier may cover the same target, but you may still need your own source for a separate fight or target.

Playing Teemo: Poison and mushroom damage can refresh healing reduction while they keep damaging a champion. This makes you a useful applier against sustain, but a trap that nobody triggers provides no coverage. Check the debuff duration after the last damage tick.

Will the fight last long enough?

If you die before dealing damage, you apply no healing reduction. If your target dies before healing, there is little healing to prevent. The debuff applies on qualifying damage immediately; it does not need to build up. It remains briefly after your last hit, so teammates can benefit even after you disengage.

Only healing during the active debuff counts. For example, 40% reduction prevents 80 of a 200-point heal, or 400 of a 1,000-point heal, before other modifiers. Compare that with the damage, penetration or survival you delayed; neither example guarantees a kill. Healing after the debuff expires is unaffected.

See the Oblivion Orb and Morellonomicon references for current effects and queue availability. These are situational decisions, not a measured best-build claim.

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

Guerrilla Warfare

What it doesIf Teemo stands still and takes no actions for a short duration, he becomes Invisible indefinitely. If he's in brush, Teemo can enter and maintain his Invisibility while moving. After leaving Invisibility, Teemo gains the Element of Surprise, increasing his Attack Speed for a few seconds.

Practical readGuerrilla Warfare is an automatic part of the kit involving basic-attack interaction. Track when its condition is active instead of treating every fight the same way.

What it doesTeemo scampers around, passively increasing his Move Speed until he is struck by an enemy champion or turret. Teemo can sprint to gain bonus Move Speed that isn't stopped by being struck for a short time.

What it doesTeemo throws an explosive poisonous trap using one of the mushrooms stored in his pack. If an enemy steps on the trap, it will release a poisonous cloud, slowing enemies and damaging them over time. If Teemo throws a mushroom onto another mushroom it will bounce, gaining additional range.

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

Trade around health, range and the next wave

1
Wave

Let the team clear without spending every important cooldown at once.

2
Map play

Track the shared lane, brush control and available relics rather than looking for a Rift rotation.

3
Fights

Use the champion's reliable range, protection or control before forcing a low-percentage engage.

Shared-lane plan

Teemo 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.

ARAM only
1
Before the fight

Clear or escort the wave, check which allies are alive and preserve enough health to use the champion's reliable range, protection or engage.

2
During the fight

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.

3
After the fight

Push with surviving minions, take the safe structure damage available and reset only through a real death rather than donating one alone.

Keep preparing

Stay inside the ARAM ruleset
