Complete breakdown of the #1 unit in UTD. Mana system, Shadow Legion/Domain mechanics, soldier inheritance formulas, and optimal positioning strategies.
Data Verification Notice
Some SJW values have known discrepancies between documentation and in-game behavior. Specifically, Mana costs (70k) exceed documented Mana cap (6k). This guide marks uncertain values with ⚠️. Please verify critical numbers in-game.
TL;DR - Why SJW is #1
Strengths:
- • Hybrid attacker (Air + Ground)
- • Army of soldiers = massive DPS
- • Domain buffs entire team
- • Works with Fortune card (2 SJW)
Build Priority:
- • E-Level: E6 > E4 (mana reduction)
- • Trait: Ruler > Sacred
- • Relics: Damage > Cooldown
- • Position: Front for Mana, Mid for safety

Evolution Level Breakdown
Base SJW
- Mana system: kills grant 20 Mana
- Shadow Legion: summons 15 shadow soldiers
- Shadow Domain: area buff zone
- Hybrid attacker (Air + Ground)
Usable but soldiers are weak without E4 HP bonus.
Evolved SJW
- All E0 effects
- Shadow Legion summons 25 soldiers (up from 15)
- +10 additional soldiers per cast
- Improved base stats
Big soldier count increase. Good stopping point for budget builds.
Shadow Monarch
✓ RECOMMENDED- All E2 effects
- +75% Shadow Soldier HP
- Soldiers become significantly tankier
- Domain buff greatly enhanced
Major power spike. Soldier survivability makes this essential.
Absolute Shadow Monarch
✓ RECOMMENDED- All E4 effects
- 50% Mana cost reduction on all skills
- Shadow Legion: 70k → 35k Mana
- Shadow Domain: 40k → 20k Mana
- Much faster skill rotation
Best in slot. Mana reduction enables constant army uptime.
Positioning Strategies
Front Line Deploy
Place SJW near spawn to maximize Mana from early kills
- • Fast Mana generation
- • Early soldier army
- • Good for wave clear
- • Soldiers may die to bosses
- • Need fallback DPS
Mid Line Support
Place behind main DPS, soldiers supplement damage
- • Safer positioning
- • Soldiers as extra DPS
- • Domain buffs core team
- • Slower Mana generation
- • Limited early impact
Domain Overlap
Position Domain to cover main DPS units
- • Team-wide buffs
- • Synergy with Ace/Kyito
- • Multiplies team damage
- • Requires careful placement
- • Domain has cooldown
Best Synergies
✓ Works Well With
- • Fortune Card — Double SJW = double army
- • Virtual Idol — Buffs all soldiers
- • Kapachi — +50% damage amp
- • Berserker — Armor break for soldiers
⚠️ Avoid
- • Maps with heavy AOE enemy attacks
- • Short burst fights (no time for army)
- • Modes that prevent unit placement
