Patch 18.6 follow-up — November 10, 2026
Riot’s November 6 and November 10 mid-patch updates focus on fixes and client-side changes. They announce no change to Inferno’s Burn breakpoints, Sunfire Cape’s Burn, or their stacking interaction, and the released 18.6 notes list no standard craftable-item recipe or balance change. The 18.5 item baseline and 18.3 Inferno values therefore remain in scope; champion, trait and Augment changes can still alter which holder benefits from an item. This guide does not claim a measured best-in-slot ranking.
Official Riot Patch 18.6 notes, published November 3 UTC / November 4 JST. Review scope: the released notes; PC/mobile regional deployment may take longer. Earlier dated sections retain their historical patch scope.
Patch 18.5 review — October 22, 2026
Inferno’s current Burn breakpoints are 1% / 1% / 3% / 4% at 2 / 3 / 5 / 7 units. Riot Patch 18.3 notes reduced the upper two values; Riot Patch 18.4 notes and Riot Patch 18.5 notes list no later change. Sunfire’s additional 1% Burn therefore gives 2% / 2% / 4% / 5% maximum-Health damage per second while both Burns affect the same target. This does not establish additive Wound percentages.
Official Riot Patch 18.5 notes. Earlier dated patch sections retain their historical scope.
Yes. Riot explicitly confirms that Sunfire Cape or another Burn source stacks with the Inferno trait in TFT Set 18.
That means an Inferno board does not automatically make Sunfire Cape redundant. If Belt plus Vest creates useful frontline power, the item’s Burn can add damage on top of Inferno rather than replacing it.
The important limit is wording: Riot confirms Burn stacking with Inferno. That statement does not automatically prove that Wound becomes stronger or that every pair of item-based Burns stacks with each other.

Current interaction check — November 10, 2026: The 18.6 notes and November 6/10 updates report no change to the confirmed Inferno/Sunfire Burn interaction. The tables below use the current 3% and 4% upper Inferno breakpoints, not the superseded 18.2 values. Source: Riot Patch 18.3 notes.
Quick Answer
Yes—Riot confirms that Sunfire Cape’s Burn and Inferno Burn stack on the same target in TFT Set 18. This adds Burn damage; the confirmation does not mean Wound percentages add together or that every item-to-item Burn pairing stacks.
- Inferno + Sunfire Cape Burn: Confirmed to stack.
- Inferno + another Burn source: Supported by Riot’s broader wording, but confirm current tooltips after balance changes.
- Two Wound effects: Do not add their percentages together from this confirmation; Riot confirms Burn stacking, not additive Wound.
- Should you slam Sunfire on Inferno? Yes when it improves frontline strength, reaches useful targets, and converts Belt plus Vest into immediate power.
Confirmed Inferno Mechanics
Riot’s official Set 18 overview lists Inferno at breakpoints 2, 3, 5, and 7. The trait applies Burn and Wound, while higher breakpoints also improve the trait’s shop effect and Burn damage.
| Breakpoint | Confirmed effect |
|---|---|
| Inferno 2 | Inferno damage applies 1% Burn and Wound. |
| Inferno 3 | Keeps the 1% Burn effect and ignites one shop slot after combat, rolling a champion one tier higher. |
| Inferno 5 | Ignites two shop slots and has 3% Burn in Patch 18.5, following the 18.3 adjustment. |
| Inferno 7 | Ignites four shop slots and has 4% Burn in Patch 18.5, following the 18.3 adjustment. |
Riot defines Burn as percent maximum-Health true damage each second and Wound as reduced healing received. The official overview then tells players to keep looking for Sunfire Cape or another Burn source because the additional Burn stacks with Inferno.
What “Burn Stacks” Means in Practice
When an enemy is affected by both Inferno Burn and Sunfire Cape Burn, both sources contribute Burn damage. Using the current Set 18 Sunfire tooltip as a working example, a 1% Sunfire Burn adds to the trait Burn while the same target is affected by both.
| Trait breakpoint | Inferno Burn | Sunfire Burn | Combined Burn on overlap |
|---|---|---|---|
| Inferno 2 | 1% | 1% | 2% max Health per second |
| Inferno 3 | 1% | 1% | 2% max Health per second |
| Inferno 5 | 3% | 1% | 4% max Health per second |
| Inferno 7 | 4% | 1% | 5% max Health per second |
These totals apply only while the same target is affected by both Burns. Holder range, timing, and target coverage still matter. The current trait values come from the 18.3 balance change, retained through 18.5; the totals are arithmetic for overlapping Inferno and 1% Sunfire Burn, not a whole-board damage estimate.
Burn and Wound Are Different Questions
Burn deals damage. Wound reduces healing. Riot’s Set 18 overview specifically confirms that an additional Burn source stacks with Inferno. It does not state that two Wound effects add together.
- Count the extra Burn damage when effects overlap.
- Use additional Wound sources for coverage, timing, or reliability.
- Do not publish additive Wound math without separate confirmation.
Why Sunfire Cape Is Not Redundant on Inferno
Sunfire contributes more than its Burn tooltip. It converts Giant’s Belt plus Chain Vest into Health, Armor, extra maximum Health, and nearby Burn/Wound application.
That creates four separate jobs: immediate frontline durability, component conversion, extra Burn that stacks with Inferno, and Wound coverage from the holder’s position.
If the holder needs Health and Armor, removing Sunfire from consideration just because the board has Inferno throws away real value.
When to Slam Sunfire Cape on an Inferno Board
Sunfire is a strong practical slam when:
- Belt and Vest are awkward leftovers.
- The board is losing HP and needs immediate frontline strength.
- A durable holder can stay close to priority enemies.
- The board needs earlier or wider Wound application.
- The extra Burn helps against high-Health frontlines.
- Saving the components would delay a useful completed item for several rounds.
- The item can transfer to a later frontline unit.

When Another Belt or Vest Item Has More Value
Burn stacking does not make Sunfire mandatory. Compare it with the board’s actual survival problem.
- Choose another route if the main tank needs raw Health more than Burn coverage.
- Against heavy physical damage, a harder armor option may create more survival.
- If Gargoyle Stoneplate gains major value from enemy targeting, it can beat the marginal Burn.
- If the intended Sunfire holder cannot remain near useful targets, the effect loses value.
- If Wound already reaches every priority target, evaluate Sunfire mainly for tank stats and extra Burn.
The choice is not “Inferno means no Sunfire.” It is “Does Sunfire’s complete package beat the best alternative for this board?”
Inferno Breakpoint Strategy
Inferno 2
At Inferno 2, the trait supplies 1% Burn. A current 1% Sunfire Burn can double the Burn on overlapping targets, making this the largest relative increase.
Inferno 3
Inferno 3 improves the shop effect rather than Burn damage, so Sunfire keeps the same overlapping Burn relationship as Inferno 2.
Inferno 5
In Patch 18.5, Inferno 5 supplies 3% Burn and reaches 4% on a target also affected by Sunfire. Sunfire still adds damage, but the trait now contributes much more of the total Burn, so holder quality and defensive opportunity cost become more important.
Inferno 7
In Patch 18.5, Inferno 7 supplies 4% Burn and reaches 5% on a target also affected by Sunfire. Sunfire can still add Burn, but the trait already supplies a major damage-over-time effect. At this point, select Sunfire mainly when its tank stats, positioning-based coverage, and extra damage beat a harder defensive option.
Sunfire Cape vs Morellonomicon on Inferno
Both items can provide Burn and Wound, but they solve different holder and coverage problems. Sunfire belongs naturally on a frontline holder and converts Belt plus Vest. Morellonomicon is more attractive when a caster can reliably hit several enemies and provide broader application.
Do not build both solely to chase more Wound. Their main distinction is holder, reach, components, and the combat role attached to the Burn.
What About Red Buff?
Riot does not name Red Buff in the specific stacking sentence, but the phrase “other source of burn” supports the interpretation that its Burn should also stack with Inferno. Treat that as a mechanics inference unless Riot or an in-client test confirms it by name.
Does Sunfire Stack With Morellonomicon or Red Buff?
The Riot source used here confirms additional Burn stacking with Inferno. It does not separately confirm every item-versus-item combination. Do not extend the statement into a universal rule for Sunfire plus Morellonomicon, Sunfire plus Red Buff, duplicate Burn items, or multiple Wound percentages without separate verification.
Positioning the Sunfire Holder
The holder must remain close enough to a useful target for the Burn application to matter. Position to reach a high-Health frontline target early, survive long enough to apply the effect, and avoid sacrificing superior tank positioning just to chase one Burn target.
Recovering From Belt Plus Vest on Inferno
Inferno makes Belt plus Vest easier to use, not harder. If those components are stranded, identify the best current holder, compare Sunfire with the best separate Belt and Vest routes, and slam when the immediate board power is worth more than waiting.

Practical Decision Table
| Situation | Recommended decision |
|---|---|
| Inferno 2, weak frontline, Belt + Vest available | Strong Sunfire slam; it adds durability and can double overlapping 1% Burn. |
| Inferno 3, board needs combat power | Evaluate like Inferno 2; the third breakpoint improves the shop, not Burn damage. |
| Inferno 5, durable holder available | Sunfire remains valid, but compare its complete package with harder tank items. |
| Inferno 7, Burn already very strong | Choose Sunfire for stats, coverage, and marginal Burn—not because the trait lacks Burn. |
| Broad caster can apply Morello to several enemies | Morello may provide better coverage than a poorly positioned Sunfire holder. |
| Wound already reaches priority targets | Value extra sources for Burn, stats, or reliability rather than assuming stronger Wound. |
Common Mistakes
Treating Inferno as a replacement for Sunfire
Riot directly states that the additional Burn stacks. Evaluate the entire item instead of deleting it from the build list.
Doubling the Wound percentage
The official confirmation is about Burn. Do not add Wound percentages without separate evidence.
Ignoring coverage
Two Burns only stack on a target affected by both. Holder range, ability reach, and timing determine whether overlap occurs.
Forcing Sunfire at Inferno 7
The item remains functional, but the trait already supplies strong Burn. Compare the added damage and tank stats with the defensive item you give up.
FAQ
Does Inferno Burn stack with Sunfire Cape in TFT Set 18?
Yes. Riot explicitly confirms that Sunfire Cape or another Burn source stacks with Inferno.
Does Inferno make Sunfire Cape useless?
No. Sunfire still provides tank stats, local Wound coverage, and additional Burn damage on overlapping targets.
Does Inferno Wound stack with Sunfire Wound?
Riot’s overview confirms Burn stacking, not additive Wound percentages.
Does Morellonomicon stack with Inferno?
Riot names Morellonomicon in the Inferno explanation and says an additional Burn source stacks with the trait. Morello remains practical when a caster provides better coverage.
Does Red Buff stack with Inferno?
Riot’s general wording supports that interpretation, but Red Buff is not named in the specific sentence. Treat it as an inference pending direct confirmation.

Final Takeaway
Inferno and Sunfire Cape Burns stack in TFT Set 18. That keeps Belt plus Vest as a valid tempo and recovery slam on Inferno boards. Choose Sunfire when its holder, tank stats, local coverage, and added Burn improve the board—not because the trait lacks Burn, and not because two Wound labels should be added together.
The clean rule is: stack the Burn, compare the coverage, and judge the full item.
