Ethereal Joan — Character Guide
Core Mechanic: Talent - Electro Surge
Joan's core gameplay revolves entirely around her Talent: Electro Surge, which provides two major mechanics: Thunderflow and Overcharge. While she has other skills (Ultimate, Special, Basic ATK), her strength is determined by this talent system.
Thunderflow
When Joan's HP falls below 60%, she automatically activates Thunderflow for 10 seconds.
During Thunderflow:
- Becomes invincible (immune to damage, HP loss, and control effects)
- CRIT Rate +30%
- All allies receive All Damage Taken Down (Moderate)
Note: Without Spirit Siphon Tier 5, Thunderflow can only trigger once per battle.
Electro Capacity and Overcharge
Joan accumulates Electro Capacity by dealing damage. Dealing damage equal to 1000% of her base Max HP fully charges Electro Capacity and triggers Overcharge.
Overcharge duration: 18 seconds
During Overcharge:
- Total damage dealt +50%
- Basic and Special ATK coefficients ×1.5
- After casting any skill, Joan deals additional piercing damage equal to 20% of that skill's damage to all enemies
- Each skill cast applies 1 stack of Thunderbrand
After Overcharge ends:
- Electro Capacity accumulation restarts
- 6-second cooldown before Overcharge can be triggered again
Static Overflow (Spirit Siphon) — Critical Upgrade
Static Overflow provides an alternate way to charge Electro Capacity. This is essential for Joan to be functional in practice.
- Level 1: Instantly grants 70% Electro Capacity
- Level 2: Instantly grants 85% Electro Capacity
- Level 3: Instantly grants 100% Electro Capacity when Thunderflow activates
Without Static Overflow Level 3, Electro Capacity charging is too slow for practical use.
Thunderbrand
Thunderbrand is applied during Overcharge when Joan casts skills. At 5 stacks, Thunderbrand converts into a 1-second stun.
Other Notable Features
- All of Joan's attacks deal piercing damage
- Ultimate: fan-shaped AoE stun lasting 2 seconds
Common Team Composition

Investment Guide
F2P / Light Spender
- One copy for collection only
Minimum Functional
- Spirit Siphon Tier 1 + Static Overflow Level 3 (required)
Mid-Spender (PvP)
Heavy Spender

Important Warning
Without Spirit Siphon Tier 1 and Static Overflow Level 3, other characters will outperform her.
Ethereal Joan requires heavy investment to function properly, but when fully built, she becomes a powerful tank and DPS hybrid with strong control.
