Xun, the time witch and Ebon boss lady, delivers strong burst through time stop and a shared energy bar for her orbit shift skill and ultimate. This guide covers her signature arc disk, practical rotations, team options, and awakening choices.
Signature Arc Disk and Lower-Tier Alternatives
Xun’s signature arc disk “Wandering Beyond Time” boosts attack by 16% and builds up to three “barren time” stacks whenever teammates use orbit shift or assist skills. Consuming all stacks on ultimate grants 24% crit damage plus 8% per stack, reaching 48% crit damage and 12% defense ignore for 70 seconds when fully stacked. The long duration means one opening rotation covers multiple ultimates.
The strongest accessible replacement is the 5-star monthly card arc disk “Fearless Slumber” at max breakthrough, hitting roughly 84% of signature performance. The protagonist’s paid signature “World-Turning Rain” reaches about 84% as well. “Haitelo’s Peace” from the Justice Execution boss fight sits at 82% and serves as a reliable floor option since you can eventually clear it.
Between signature arc disk and awakening, awakening edges ahead. The sixth awakening node (30% defense ignore during time stop) outperforms the signature on paper, and keys for awakening are plentiful through gacha byproducts and events.
E-Skill Recording Rules and Limits
Xun’s orbit shift skill consumes half her non-closed chronometer bar, deals seven hits of light damage, and records up to three teammate orbit shift or assist skills cast in the next five seconds. Each character can be recorded only once, and recorded skills move with enemies so positioning is rarely an issue.
You can even replay secondary effects such as Nana Li’s creation flowers or Adler’s shields, but crowd-control skills fail because time stop freezes targets in place. If no strong teammate skills are available, skip the E skill entirely—its energy cost equals half an ultimate, so only copy something worth at least that value.
Ultimate Flow and Time-Stop Combat
Once the non-closed chronometer fills, Xun’s ultimate opens with a cross-shaped hit, then lets her slash ten times with the drawn blade while the entire duration remains frozen. Deep Abyss timers do not advance, and you can freely switch targets mid-slash to focus elites first. The final closing hit lands after the tenth slash.
Two passives help: one doubles ultimate damage multiplier, the other lets assist skills continue attacking during time stop. Because time stop does not pause monster spawns, you can finish one wave and immediately start the next even if their health bars have not appeared yet.
Team Building and 30-Second Rotation Examples
Xun slots into most teams as a quick-swap burst unit. For mob clears bring one crowd controller, one on-field DPS, and either a buffer, sustain, or the protagonist. Drop the crowd controller against bosses and add another support or sustain instead.
Void Screen set “Lost Radiance” is the clear choice for the 25% defense ignore on ultimate. Main stats favor light damage or crit; sub-stats prioritize crit and damage bonus if Haniya is present, otherwise attack percent works nearly as well.
Without the signature arc disk, simply swap in, crowd control, ultimate, then let your on-field DPS work for one rotation before repeating. With the signature, open by recording three skills (Xun E, teammate E, Nana Li assist + E), ultimate, then let the main DPS take over until energy returns. One full stack lasts long enough for two to three ultimates in most content.
Awakening Priority and Long-Term Value
The top node to unlock first is the sixth awakening (30% defense ignore during time stop). Second priority is the flat 20% damage during time stop. Third is the team-wide 15% damage when only one enemy remains. The energy-recovery node on a 60-second cooldown is situational and best left for manual optimization later.
Three-star and six-star awakenings add one skill level and 30% team attack respectively—solid but lower priority than the damage nodes above.
Key Takeaways
Xun’s shared energy bar and recording mechanic reward thoughtful teammate selection more than spamming E every rotation. Prioritize the sixth awakening, slot her as a high-damage quick-swap, and enjoy the 70-second buff window that covers multiple ultimates. In the current early-game meta with limited strong E-skill DPS units, treating her primarily as burst output is the simplest and strongest approach.
