Lost Sword Stage 60-20 Team Build and Clear Strategy

To clear Stage 60-20 in Lost Sword, replace pure glass-cannon formations with a balanced frontline sustain team. This encounter features high incoming burst damage and multi-target cleaves that quickly eliminate unassisted mid-row and backline units. Surviving requires dedicated frontline mitigation, steady healing, and manual control over your skill activations.

Stage 60-20 Requirements and Obstacles

Stage 60-20 acts as a significant progression gate due to two primary obstacles:

Initial Wave Burst: Incoming attacks strike your frontline hard and cleave into mid-row units. Without immediate damage reduction, shielding, or crowd control at the start, your vanguard can collapse within seconds.
Effective Health Pools: Enemy waves possess substantial health pools. Relying entirely on defensive support without adequate sustained damage will cause the battle timer to run out before you clear the board.

The key to clearing the stage is maintaining just enough frontline defense to survive heavy hits while dedicating the remaining slots to sustained damage output.

Recommended Deck Composition

A reliable team setup for Stage 60-20 balances defensive anchors, buff utility, and focused single-target elimination.

Role	Recommended Options	Tactical Purpose
Main Tank	Galahad / High-Defense Vanguard	Anchors enemy aggro, absorbs initial burst, and provides personal damage reduction or shields.
Primary Healer	Dian Cecht / Lilia	Supplies burst healing, cleanses debuffs, and sustains the frontline through multi-hit combos.
Sub-Support	Lueria / Secondary Utility Buffer	Accelerates ultimate gauge generation, provides secondary heals, and amplifies team damage.
Main DPS	Single-Target / Pierce DPS Carry	Burns down priority elites and tanks before your defensive buffs expire.
Flex DPS / CC	Crassa / AoE Burst Hero	Applies staggers, disrupts enemy formations, and clears additional wave spawns.

If your frontline unit falls early, swap a secondary offensive hero for an extra support or defensive sub-DPS.

Positioning and Pet Setup

Position your primary tank in the forward-most slot to catch direct collisions and cone cleaves, keeping attacks angled away from fragile damage dealers. Prevent your frontline from being pushed backward, as spatial compression allows enemy area-of-effect skills to reach backline healers.

Equip your tank with gear focusing on flat defense, damage reduction percentages, and health substats. To complement these stats, configure your pets to bridge cooldown intervals:

Shielding and Sustain Pets: Prioritize pets that provide immediate combat-start barriers or percentage-based healing over offensive pets.
Skill Haste and Energy Utility: Use pets that grant ultimate energy generation to ensure healers can cycle abilities before the enemy's second damage rotation.
Pet Sub-Stats: Focus on health percentages, damage reduction, and crowd-control resistance to avoid rotation locks.

Manual Execution Steps

Attempting Stage 60-20 at or near the combat power requirement strongly favors manual skill intervention over auto-battle. AI targeting frequently wastes high-potency heals on light chip damage or triggers damage bursts into enemy invulnerability windows.

Hold Heals for Enemy Burst Windows: Do not trigger healing ultimates prematurely. Watch enemy attack animations and deploy your primary heal immediately after the main burst connects.
Synchronize Buffs with Damage Ultimates: Activate attack buffs and defense-lowering skills right before firing your main damage dealer's abilities to maximize output within tight damage windows.
Interrupt High-Threat Channels: Save stuns, knockbacks, or disruption skills for visible enemy channel bars to nullify heavy area-of-effect attacks.
Focus High-Threat Targets First: Direct single-target skills at backline casters or high-damage flankers rather than spreading damage across the entire wave.
