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.

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.

Repeated spell damage and damage over time can maintain coverage more reliably than a single hit. Match the purchase to your actual spell access, enemy sustain and the teammates who can apply the debuff.

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.

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

Balance lane pressure with protection for the carry

Lane

Hold the ability that makes opponents respect your lane and trade when both Bot-lane partners are ready.

Map play

Recall and move on safe wave timings; an unsupported roam can cost the carry an entire wave or a dive.

Fights

Control one approach and keep enough protection for the enemy's most likely engage.

Pings, movement and objectives

Heimerdinger Support map plan

Turn information into a shared decision. Move with an ally and preserve the tool that makes the next fight safe.

Ahead

Make the lead open the map

Ping: Use On My Way before changing angle, then Assist Me on Dragon after Bot is safe to move. Use Danger if the carry starts following through an unsafe route.
Map movement: Roam after a pushed wave, shared recall or when the carry can collect safely. Deep wards still require the Jungler or another nearby ally.
Objective: Arrive early, clear the enemy entrance and hold the key engage or peel spell. Do not chase away from Dragon and hand the opponent a free route back in.

Even

Create one clear numbers advantage

Ping: Use On My Way before an engage or roam, Enemy Missing as soon as a lane opponent disappears, and Danger when your carry cannot follow.
Map movement: Leave only on a safe wave or recall timing. If the carry would lose a full wave or face a dive, stay Bot and communicate that you are not moving.
Objective: Help Bot finish the wave, then enter river with the Jungler. Set vision before starting and avoid turning an even objective into an unseen gamble.

Behind

Stop the next loss before seeking a play

Ping: Use Retreat or Danger before an ally enters darkness, Enemy Missing immediately, and Assist Me when you need company to restore defensive vision.
Map movement: Do not abandon a crashing wave or vulnerable carry. Move after the wave is stable and use the nearest safe ward line rather than forcing deep vision.
Objective: If your team cannot enter river safely, ping Retreat and trade for farm, vision or another map resource. Contest only after creating a safe route together.

Objective setup

Four calls, in order

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

1
Before the move
Around a minute before Dragon, ping the plan, spend gold if needed and make sure Bot and Mid know whether they can move.
2
Enter together
Walk with the Jungler or another ally. Sweep one route, place useful entrance vision and never face-check alone.
3
Before starting
Check nearby waves and enemy positions. Hold the spell that either starts a reachable fight or protects your main damage dealer.
4
During the contest
Keep enemies away from the safe entrance, mark the reachable threat and avoid chasing so far that Dragon is left unprotected.

Later objectives: Use the same pattern for Rift Herald or Baron: communicate first, move through controlled vision with an ally, then choose engage or peel before the fight begins.
