Sion is a Shock support who excels at grouping dense enemy clusters and setting up AoE burst for allies. His sacred relic deals damage and applies Shock on both deployment and retrieval. While currently ranked B-tier, he far exceeds that rating against grouped enemies and is the hero most likely to rise as players discover optimal team compositions. Pair him with Ornette and Tarte for the dedicated Shock team, or with Lute for a balanced build.

⚡ Combat Style
Sion's core mechanic is his sacred relic (성물), a deployable field that groups enemies together. The relic deals damage and applies Shock judgment on both deployment and retrieval — meaning you get two Shock applications per use by recalling it at the right time.
This makes Sion exceptional against dense enemy groups: he clusters them together, applies Shock, and creates a window for AoE-focused allies like Ornette to unleash burst damage. His value is highly scenario-dependent — against single targets or spread-out enemies, his grouping utility is wasted.
⚔️ Best Build
Shock Support Build (Recommended)
Gear Sets
3-piece Thunderrush + 2-piece Ruinsbreaker (or Shock 3 + Down 2)
Thunderrush boosts Shock damage and ailment speed. Ruinsbreaker adds DEF Ignore. Alternative: Shock 3 + Knockdown 2 if focusing on knockdown chains.
Main Stats
ATK Power Up → Critical Hit Chance → Critical DMG
For a support-focused build: ATK Speed, ailment application rate
Skill Priority
Prioritize the attack branch damage nodes and crit-related passives. Focus on core passives over long-cooldown actives.
👥 Best Team Compositions
| Team | Best For | Sion's Role |
|---|---|---|
| Ornette + Tarte + Sion | Dense groups / AoE stages | Groups enemies and applies Shock; Ornette follows with AoE burst |

| Sion + Tarte + Lute | Survival-focused Shock | Grouping and Shock; Tarte and Lute provide sustain |
Ornette + Tarte + Sion — Shock Team Loop
- Sion deploys sacred relic to group enemies and apply first Shock
- Tarte stacks additional Shock debuffs on the grouped cluster
- Sion retrieves the relic for a second Shock application and damage hit
- Ornette switches in with wide scythe AoE on the clustered, shocked enemies
- Chain Signal Skills off the Shock window for burst damage
✅ Strengths
Enemy Grouping
Sacred relic pulls enemies together, creating ideal AoE opportunities for allies.
Double Shock Application
Relic applies Shock on both deployment and retrieval — two ailment hits per use.
High Growth Potential
Most likely hero to rise in tier rankings as team compositions are optimized.
Dense Group Specialist
Far exceeds B-tier rating against clustered enemies in mob-heavy content.
❌ Weaknesses
- Scenario-dependent — Grouping is useless against single bosses or spread-out enemies
- Lower personal damage — Primarily a support/setup hero, not a main DPS
- Requires team coordination — Needs allies who can capitalize on grouped, shocked enemies
- B-tier baseline — Against single-target content, other heroes outperform him
🎮 Combat Tips
- Deploy and retrieve — Remember the relic applies Shock twice: on deployment and on retrieval. Time the recall for maximum value.
- Group before burst — Let Sion cluster enemies first, then switch to Ornette or another AoE DPS
- Use in mob-heavy content — Sion shines in stages with dense enemy groups. For single-target boss fights, consider other supports.
- Pair with Tarte — Tarte is essential for stacking Shock quickly on the grouped cluster
- Don't sleep on him — Despite B-tier ranking, Sion's grouping is unique and irreplaceable in the right content
