Buying anti-heal does not mean the enemy’s next heal gets smaller. You still have to apply the debuff to the champion receiving that heal, and the heal must happen before it wears off.
Grievous Wounds currently reduces healing and health regeneration received by 40%. Affected healing keeps 60% of its value. The standard anti-heal items apply it for three seconds, with different triggers for physical damage, magic damage, and an enemy attacking you. An item with the wrong trigger can leave your intended target unaffected. Riot’s current item data supplies the item values; the League Wiki’s Grievous Wounds reference documents the debuff’s recipient and overlap rules.
This is an application and buying guide for standard PC Summoner’s Rift. It does not rank items by win rate.
What 40% healing reduction actually prevents
Suppose an enemy would receive a 400-health heal without Grievous Wounds. If the debuff is active, that becomes:
400 × 0.60 = 240 healing. You prevent 160.
For this example, 400 is the heal after any other relevant healing modifiers, the champion is missing enough health to receive it all, and nothing else changes between the two cases. These are hypothetical amounts, not measurements of a particular champion’s spell.
Now change one assumption: the champion is missing only 100 health. A nominal 400 heal and a reduced 240 heal both fill that gap. In this isolated example, anti-heal changes the nominal amount but prevents zero actual health recovered. There is no overheal-to-shield effect in this calculation.
For an ordinary heal capped by missing health, compare what the target can actually receive:
Health denied = min(missing health, normal heal) − min(missing health, normal heal × 0.60).
This does not make Grievous Wounds useless against someone near full health. Damage during a fight can create a much larger gap before their next heal. It does mean that “40% of the heal’s tooltip” is not always health you would otherwise have needed to remove.
Healing denied is not bonus damage. If the target dies before a heal arrives, there was no heal for the debuff to reduce. If the target gets a large heal during the fight, it can matter considerably. The purchase depends on the healing your team is actually allowing the enemy to receive.
One hit is not coverage for the whole fight
Here is a second hypothetical example. An enemy receives two separate 200-health heals. They are missing enough health for both, and your item applies Wounds for three seconds:
- At 0 seconds, you land a hit that triggers your item’s anti-heal.
- At 1 second, the first heal arrives. It restores 120, preventing 80.
- At 4 seconds, the second heal arrives. Your debuff has expired, so it restores the full 200.
The enemy receives 320 of the original 400 total healing. You prevented 80, or 20% of the combined amount, even though the debuff’s strength is still 40%.
Now add another qualifying hit at 2.5 seconds. The renewed window lasts until 5.5 seconds and covers the heal at 4 seconds, so both heals restore 120: 240 total received, 160 prevented. The extra application improves coverage; it does not make either heal suffer a stronger reduction.
A retreat can leave the important heal uncovered even if you landed the opening hit. Do not chase into a losing position just to refresh Wounds. Instead, account for that gap when deciding whether you or a teammate can handle the job.
Debuff the patient, not automatically the healer
Soraka makes the targeting mistake easy to see. Her Astral Infusion heals another allied champion. If she heals the enemy carry, Grievous Wounds needs to be on that carry to reduce the healing received. Applying it only to Soraka does not reduce the heal she sends to someone else.
Consider a fight where your team is hitting the enemy frontliner while Soraka stands behind them. Your mage can reach the frontliner with magic damage but cannot safely get past them. Oblivion Orb can help reduce the healing that frontliner receives. Running around the fight to tag Soraka instead would not accomplish the same task.
There are still excellent reasons to attack Soraka. Forcing her away from an ally or killing her can prevent healing altogether. The mistake is treating “hit the healer” as the trigger for reducing every heal she casts. Decide whether you are denying her access or reducing healing on the target your team is already fighting.
For self-healing, the source and recipient are the same champion, so this distinction is less noticeable. The enemy’s build matters too: healing from life steal is also reduced while Wounds is active, so the target does not need a dedicated healing spell. In the Soraka matchup, your item can be correct and your target still wrong.
Which anti-heal item can you actually apply?
All three components below cost 800 gold in the current Summoner’s Rift data. Each applies 40% Grievous Wounds for three seconds. Their listed completed items retain that same percentage and duration; completion is not an upgrade to 60%.
| Application route | Component → completed options | What must happen |
|---|---|---|
| Physical damage | Executioner’s Calling → Mortal Reminder or Chempunk Chainsword | You deal physical damage to the enemy champion. |
| Magic damage | Oblivion Orb → Morellonomicon | You deal magic damage to the enemy champion. |
| Being attacked | Bramble Vest → Thornmail | The enemy champion hits you with an attack. |
The current Riot item descriptions support these triggers, costs, and paths. Choose a route that fits both your champion and the opponent you need to affect.
Executioner’s Calling: damage type, not just basic attacks
Executioner’s Calling applies through physical damage, so a physical-damage ability can qualify as well as an appropriate basic attack. “I bought AD” is not the rule; the damage that reaches the enemy must satisfy the item’s trigger.
Consider the component when you can keep attacking the healing target and can afford to delay your next purchase. It is less convincing when the enemy who needs anti-heal is outside your safe reach and you spend the fight hitting someone else.
The two completed paths serve different builds. Mortal Reminder combines attack damage, armor penetration, and critical strike chance. Chempunk Chainsword combines attack damage, health, and ability haste. Do not buy the latter on every physical-damage champion merely because it also says Wounds; those other stats determine how well the full item fits.
Oblivion Orb: someone has to land magic damage
Oblivion Orb requires magic damage to the enemy champion. Healing or shielding your own ally is not an application. Nor does simply having ability power make every part of your kit deal magic damage.
A mage who can hit several enemies may cover more healing recipients than a teammate restricted to one target. That is useful coverage, not a reason to spend every spell spreading the debuff. Hitting three enemies who are not about to heal can be less valuable than reaching the one enemy your team needs to kill.
Morellonomicon adds ability power, health, and ability haste, but its anti-heal remains 40%. Also, do not follow an old support build into Chemtech Putrifier: its retained current item record is marked not purchasable and not in store. An old guide or a leftover database entry is not a current shop option.
Bramble Vest: the enemy helps decide who gets wounded
Bramble Vest and Thornmail apply to an enemy champion who attacks their wearer. They are not an aura that wounds everyone nearby. Your own crowd control does not substitute for the enemy’s attack.
“The tank will buy anti-heal” leaves a crucial question unanswered: will the right enemy attack the tank? If the enemy carry attacks your tank, the carry can receive the debuff. If the same carry ignores the tank and attacks your ADC, that particular trigger does nothing to the carry. Against an enemy who is healing while avoiding attacks on you, buying more armor does not fix the application problem.
Current Thornmail also does not apply Grievous Wounds merely because you immobilize someone. Riot removed that route in patch 13.1B. A stun can make a target easier for a teammate to hit, but it does not turn Thornmail into unconditional anti-heal.
Two buyers do not make it 80%
Grievous Wounds does not stack into a stronger reduction. Two 40% applications do not produce 80%, and they do not multiply into 64% either. The effect stays at 40%; separate sources can overlap, while another application from the same effect refreshes its duration. That distinction is documented in the League Wiki’s non-stacking notes.
So should only one person buy it? Often one reliable applier is enough for a particular target. It is not a rule for the whole map.
A second buyer can make sense when two healing enemies fight in different places, your first applier cannot reach the next target, or the teammate covering the debuff is likely to be forced out early. Conversely, two teammates continuously applying it to the same enemy are not doubling the healing denied.
Ask for a job, not five purchases: “Can you keep Wounds on the frontliner while we hit them?” Before spending another 800 gold, check whether your purchase adds a target or a window the team currently misses.
Ignite covers a window, not every later heal
Ignite’s current tooltip applies Grievous Wounds for its five-second duration. That gives a team another source to consider before buying an item, but it is not always available and does not cover a heal that happens after the effect ends.
If reducing a particular heal is important to the kill, apply Ignite before that heal rather than after watching the health bar jump. There may be reasons to hold it for a different target or use it for damage; the anti-heal decision is about which healing event it can still affect.
Shields are two different questions
Does Grievous Wounds reduce the shield itself? No. Healing reduction is not shield reduction. A shielded enemy can remain difficult to kill even while their healing is being reduced.
Can you apply item anti-heal through an ordinary shield? Yes, for the damage-triggered items discussed here. Riot changed them in patch 13.7 so they apply Grievous Wounds even when a shield absorbs all of the qualifying damage. You do not have to break a normal shield first to reduce an incoming heal.
Riot’s same note preserves the exceptions for invulnerability and damage blocked by a spell shield. A normal damage-absorbing shield and a spell shield are not interchangeable mechanics.
Not every sudden increase in the health bar is healing, either. Lulu’s Wild Growth grants bonus maximum health; Grievous Wounds does not shrink that health grant. Identify what kept the target alive before buying the answer to a different problem.
Buy coverage before buying a completed item
An 800-gold component already supplies the full 40% reduction. Completing its item adds stats and the other benefits listed on that item, not a stronger version of Wounds. Riot’s 13.1B anti-heal changes deliberately made the component a usable stopping point.
Holding that component can make sense when healing is deciding fights now, you can apply it reliably, and your next core item remains important. Finishing immediately can make sense when the complete item’s stats fit your build and the purchase solves more than the healing problem. There is no universal rule that anti-heal must be your first, second, or last item.
Sometimes the right purchase is no anti-heal item. Delay or skip it when the relevant healing happens after your debuff expires, a teammate already covers the same target, or you cannot apply your chosen trigger without taking a worse fight. If you die before you can contribute, survivability or positioning may matter more. If the enemy escapes and heals safely later, a brief mark from an earlier trade will not follow them indefinitely.
But do not turn that into an excuse to ignore repeated healing. If a reachable enemy keeps healing through extended fights, refusing a component can waste the damage you already bought. Compare the next fight you expect, not the largest healing number you remember from the last one.
Before recalling, name three things: the enemy who needs the debuff, the action that will apply it, and the heal you expect to catch. If you can answer all three, compare that benefit with the purchase you would delay. If you cannot, start there instead of buying it out of frustration.
