Combat systems: Lingya, ability rhythm and domain duels

Fights in Sword of Immortality look automatic until you notice the three clocks running underneath: the Lingya check at the start, the ~3.5-second ability cadence, and the ten-cast domain timer. Win the first and the other two become easier; lose it and you spend the opening seconds stunned while the opponent's domain comes online.

What is Lingya, exactly?

Lingya is not a hidden power score. It is a straight sum: total Lingya equals the combined Lingya value of every flying fabao you have equipped. Nothing else feeds the number. That definition has two consequences that most guides miss.

• Lingya is a loadout stat. Swap a fabao out and your Lingya changes immediately. There is no permanent progression track called Lingya to grind.
• More fabao is not automatically better. The sum rewards the fabao you actually fly, so a smaller number of high-value pieces can beat a wide spread of low ones.

When a page or a video says to “raise Lingya”, it means upgrade or swap flying fabao — not spend a currency with that name.

How long does the stun last?

The higher-Lingya side stuns the lower side. Base duration is three seconds, and each 1% of Lingya lead adds 1% of that base — capped at six seconds.

Lingya gap	Stun	First shield layer removed
0% (even)	3.00 s	20%
+25%	3.75 s	45%
+50%	4.50 s	70%
+75%	5.25 s	95%
+80%	5.40 s	100% (cap)
+100% or more	6.00 s (cap)	100%

The math is linear, so the decision is simple: the first 50% of a Lingya lead buys you 1.5 extra seconds, and the next 50% buys the same again but also takes the shield strip from 70% to full. If you can choose between a small lead and a large one, the large one is worth more than the raw percentage suggests.

How does the shield strip work?

The same gap that sets the stun also removes a share of the loser's first shield layer: 20% base, plus 1% per 1% gap, capped at 100%. At an 80% lead the first layer is gone entirely. This is why Lingya feels stronger than its raw number suggests — the winner does not just act first, they delete a defensive layer before the first trade.

Against bosses and elite targets, the same rule applies. If a target out-Lingyas you, expect to lose a shield layer and eat a stun before your first ability resolves. Build for Lingya when a specific boss keeps opening with a stun that costs you the run.

How do fabao change ability rhythm?

Left alone, abilities fire about every 3.5 seconds. Fabao collisions interrupt that cadence and push the next ability back. The corpus gives two placement rules:

• If your abilities are well developed, place fabao later in the sequence so their collisions cannot delay your main damage.
• If your fabao damage far exceeds your ability damage, front-load them instead, because the fabao are the damage.

That is a threshold question, not a preference. Compare the two damage numbers in your own build; whichever is larger should get the earlier, cleaner window.

What are the four domains?

Ten total ability or fabao casts trigger your domain. Whether it intrudes depends on aura pressure: any lead over the target triggers the check. The 5% figure that circulates in guides is the Dominator Dao's stricter rule, not a universal threshold. Once intrusion lands, each domain applies a different effect.

Domain	Own effect	Intrusion effect
Shenxiao	Duel-oriented	Stuns the target for 5 seconds — the “five-second silence”
Shahai	Adds damage based on max HP	Costs 15% true essence; target takes +20% damage
Zhenyang	Damage up while at 70% HP or more	Lowers the target's ability and fabao damage
Zhan Tian	Amplification and reduction stack up to 3	Target takes +15% damage plus 60% attack damage per second

Shenxiao is the duelist's choice because a five-second stun is long enough to land a full rotation. Shahai trades your resource for a damage-taken debuff, which suits long fights. Zhenyang asks you to stay healthy, so it rewards builds that can avoid the opening burst. Zhan Tian unlocks only at Mahayana and is the only domain that keeps ticking damage after intrusion.

The pressure check is the gate. A domain that cannot intrude still gives its own effect but does nothing to the opponent, so a domain choice without the pressure to back it up is half a system.

Which official clarifications change a fight?

Five design-FAQ rulings are easy to miss, and each flips a common assumption:

• Lieshen's amplification applies to the Leiyu magic shield. Sword players cannot assume their debuff is wasted on thunder builds.
• Umbrella shatter is multi-hit, and each hit is reduced separately. A single big reduction does not blunt the whole sequence.
• Fenxin healing scales with maximum true essence, not with damage dealt. Stacking max essence is a defensive choice for fire.
• Duizui's judgement applies to the next ability, not to the one that applied it. Order matters.
• Half-HP damage reduction is checked before the hit lands, not after. A hit that would cross the threshold does not get the reduction.

How do you beat a higher-power opponent?

The corpus records two opening sequences for upset wins. Both depend on eating the first combo rather than racing it.

Thunder-sword against Guling: open with Vanguard Guard to pre-shield, move to Thunder Spirit Shadow and flank, then chain Nine Heavens Thunder Call into Ten Thousand Swords Heavenly Thunder. The point is to arrive at the paralysis window with your ultimate still available, then finish with Residual Thunder Reap.

Tiangang sword against thunder: open with the body-guard reduction to absorb the first set, watch for the gap after the thunderstorm ends, close during that gap, break defence, and land Tiangang Absolute Sword. The whole plan is built around one observable event — the storm ending.

What should you practise first?

Three drills, in order: check your Lingya before every duel and swap fabao if the gap is unwinnable; time a full rotation against the 3.5-second cadence without clipping your own abilities with fabao; and count to ten casts to know when your domain is about to trigger. Those three habits matter more than any single build string, and they carry across every patch. The build library supplies the rotations; this page supplies the clock they run on.
