Mana Lock: Why More Attack Speed May Not Mean More Casts

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.

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: If a caster spends substantial time in an animation or mana-locked state, extra attack speed or mana generation may produce less cast frequency than expected. Observe completed spells, not only the mana-rate estimate.

Set 18 · Patch 18.5 · reviewed October 22, 2026. Decision guide.

A spell cycle has more than a mana bar

A caster needs to acquire mana, start an ability and complete the relevant animation. Depending on the champion, parts of that cycle can restrict mana gain or delay the next action. A simple resource-per-second calculation does not describe every step.

The August 28, 2026 Set 18 community mana-lock discussion highlights this exact concern. The author also acknowledged errors in parsing some data. We use it as a reason to inspect timing, not as a verified table of champion-specific lock durations.

A live 18.5 example: Mama Beak

Riot moved the end of Mama Beak’s mana lock from when the Tiny Beaks finish despawning to when they start, shortening the lock by about one second. Her ability attack-damage scaling was reduced at the same time. This is a useful example of why cast access and damage per cast must be checked separately; it does not establish a measured best item build.

What to watch in combat

Observe whether the holder attacks between casts, spends time channeling, or sits near a filled mana bar while an action completes. These are different limitations. The first may respond to attack-based mana; the second may not turn extra speed into extra attacks during that period.

Also separate control and target loss from the unit’s own animation. A long pause caused by a stun is not proof of a long intrinsic mana lock. Repositioning or protection may solve a different problem from replacing the mana item.

Worked decision: a second mana item looks attractive

Your caster already has a mana item and a damage item. Nashor’s would complete the third slot, and the tool shows more additional mana. Before accepting the result, watch one comparable combat and count useful casts before the frontline dies.

Then test a damage-focused third slot in a controlled comparison. The question is whether the extra mana changes the number or timing of useful casts enough to compensate for lower damage per cast. If the unit completes the same sequence because animation time dominates, the generated-mana number did not settle the trade.

Use a proxy for the question it answers

Build Compare estimates additional item mana from modeled attacks and regeneration. It does not load real champion ability costs or mana-lock sequences. That makes it useful for asking how items change a resource route. It is not a prediction that a named caster will cast a specific number of times.

Questions players ask

Does a low maximum-mana value guarantee Nashor’s is ideal?

No. Attack activity, animation, role resource rules and other items still matter.

Can I use an old mana-lock list for the new set?

Treat it as historical until the current champion implementation is verified. This guide intentionally avoids copying exact durations.
