Double Gunblade + Blue Buff: Test the Healing Trade

Guide scope · Patch 18.6

Patch 18.6 review — November 4, 2026

The released 18.6 notes list no standard craftable-item recipe or balance change. This guide retains the checked 18.5 baseline, including its October 27 corrections where relevant. Champion, trait and Augment changes can still change which holder or board benefits from an item; this review does not establish 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.

18.5 scope: This trial uses standard Blue Buff. The 18.5 reduction from 30% to 25% base AD/AP is for Radiant Blue Buff; it is not a standard-item nerf.

Patch 18.5 review — October 22, 2026

Riot’s released 18.5 notes do not list standard craftable-item balance or recipe changes. The standard-item examples below retain their previous baseline after this patch-delta check. Champion abilities, traits, Augments and Wisps are outside the numeric sandbox; community examples keep their original dates and experimental builds are not treated as match-tested results.

Official Riot Patch 18.5 notes.

Quick answer: Treat double Gunblade plus Blue Buff as an experiment for a caster with substantial damage from its kit or team bonuses. The second healing item must earn its slot against a damage or utility alternative.

Set 18 · Patch 18.5 · reviewed October 22, 2026. Experimental build.

State the hypothesis before playing it

The proposal is that one caster can deal enough repeated damage to turn two sustain slots into meaningful additional combat time. Blue Buff is the steady-mana part of the plan. This is editorial theory, not a measured Set 18 result or a statement about how rarely the build is used.

Its hardest trade is the second Gunblade. Healing linked to damage can fall when a damage slot is replaced, so counting twice as many healing-item icons does not establish twice as much useful healing. The team also needs living recipients who can exploit the recovery.

The three observations that matter most

Watch damage before your frontline dies, useful healing received before allies die, and the carry’s contribution after the opening. A large healing total that arrives late or lands on a unit with no remaining impact may not validate the plan.

Enemy Wound, burst, backline access and your own target access change the experiment. A long fight against modest incoming pressure tests a different problem from a lobby where the carry is immediately threatened. Keep those contexts in the record.

Worked trial: compare the second Gunblade, not three new items

Start from Gunblade, Blue Buff and a damage item. Replace only that damage item with the second Gunblade in your test plan. Hold the remaining items, holder and team effects constant where possible. The question is whether added recovery compensates for the sacrificed offensive contribution.

In Component Planner, the full experimental package requires two swords, two rods and two Tears. If you have only one completed Gunblade, credit one copy. The second still needs its own sword and rod. That exact bill prevents a visually appealing build from borrowing components twice.

Use the simulator to price the lost damage

Build Compare does not simulate Gunblade’s healing. It can help estimate the offense you exchange, but it cannot announce the winner of the healing trade. For the missing half, keep a short combat note: opponent, tank survival, useful casts and where healing went. One favorable fight is a reason to test further, not a universal build rule.

Questions players ask

Does the package promise unlimited healing?

No. Healing is constrained by actual damage, valid recipients, incoming pressure and the match’s effects. No infinite loop is claimed here.

Do I need to craft both Gunblades immediately?

The idea is easiest to explore when pieces are already available. Do not ignore damage or frontline needs just to complete the experiment.
