Idle Heroes: How to Build Sword Flash Xia as a Carry

To run Sword Flash Xia as a primary carry in Idle Heroes, place her in your main Cloud Island homeowner slot, build for round-one active burst, and ensure your debuff supports move before she attacks. Xia relies on high Attack scaling, counterattacks, and targeted execution on the lowest-HP enemy to clear threats before enemy teams cycle their active skills.

Core Stat Priorities and Artifact Selection

Xia scales heavily from flat Attack transferred from tenants, which multiplies through Critical Damage, Holy Damage, and Armor Break. On her soul awakening stone and gear imprints, prioritize Critical Damage, Holy Damage, and Damage Reduction to survive counter-burst.

Match her artifact to the encounter type to balance instant burst against sustained battles:

A Splendid Melodic Strings is the standard choice for Void Campaign pushes. The instant active skill allows Xia to secure an immediate kill on round one, triggering bonus damage and defensive block stacks.

Cloud Island Homeowner and Tenant Priorities

Do not split building resources across multiple homeowner platforms. Xia must occupy the primary Homeowner slot, with Master's Eye and Aura investments concentrated into her two attack-boosting tenant slots:

1. Focus on Attack tenants: Slot heroes such as Scarlet Queen Halora and compatible Fortress heroes into her Attack-granting positions.
2. Maximize tenant stats: Equip tenants with resonance gear attuned to them, Attack/Attack stones, and full Attack imprints to maximize the shared stat pool transferred to Xia.
3. Delay defense buildings: Keep defensive tenant houses at baseline levels until your Attack houses reach the thresholds needed to one-shot enemy waves.

Support Synergies and Speed Tuning

Xia cannot secure round-one kills without debuffs applied ahead of her strike. Your supports must have higher base Speed stats than Xia so their effects land first.

• Scarlet Queen Halora (SQH): Functions as both an essential tenant and an active combat support. Her All-Damage buff and vulnerability debuff expand Xia's burst threshold.
• Drake: Applies Black Hole Mark to strip defenses and force Xia's targeted burst onto the lowest-HP target regardless of frontline positioning.
• Elena or Betty: Provide damage mitigation and crowd-control locks, preventing enemy teams from wiping Xia if a wave survives round one.
• Rogan or Heart Watcher: Act as transitional supports in early-to-mid lineups to provide speed buffs and cumulative damage amplification.

If Xia outspeeds Drake or Scarlet Queen Halora, adjust equipment, boots, or enables to ensure the supports act first. An active skill used on unstripped targets significantly reduces her snowball potential.

Void Campaign Adjustments

When facing waves with heavy crowd control or retaliation passives (such as nodes with Holmes Young, Michelle, or Garuda), adjust Xia's setup:

• Swap offensive enables for survivability: Switch damage amplification enables to Purify and unyielding shields to prevent her from being locked down by freeze, stun, or petrification.
• Let secondary supports soften targets: If frontline enemies carry damage negation shields, rely on support attacks to chip enemy health pools so Xia’s targeting naturally redirects to squishier backline units.
• Switch artifacts on extended stages: If a stage cannot be cleared in round one due to revive mechanics, switch from Melodic Strings to Antlers Cane or Punisher of Immortal to maintain damage across later rounds.
