Recommended Unit Types
💡 Strategy Tip
Deploy economy units first to afford Shimon's 10K cost, then maximize his scaling potential
Specific unit synergies need community testing verification
Deployment Strategy
1. Early Economy (Wave 1-10)
Deploy cheap money-generating units first to build economy for Shimon's 10K cost
2. Deploy Shimon (Wave 10-15)
Once you have 10K+ saved, place Shimon in optimal DPS position
3. Stack Spiral Power (Wave 15+)
Let Shimon accumulate Spiral Power while supporting with buffers and range units

Frequently Asked Questions
Is Shimon (Digger) worth getting?
Yes, if you can farm the event. Shimon is a strong S-tier unit with unique mechanics and infinite scaling potential. He's particularly valuable for Infinite mode where his Spiral Power and HP% damage shine. However, the 100K Halloween Cookie requirement is steep, so prioritize if you have time to farm during the event.
How long does it take to get Shimon?
Depends on RNG and farming efficiency. You'll need to: 1) Pull base Shimon from event banner/capsules (varies based on luck), 2) Farm 100,000 Halloween Cookies (estimated 10-20 hours of Infinite Halloween Mode), 3) Gather evolution materials. Budget at least 15-25 hours total if starting from scratch.
What's the best skill tree for Shimon?
Critical Tree is recommended. The +120% critical damage, +30% crit chance, and +32.5% range bonuses synergize perfectly with Shimon's high damage scaling from Spiral Power. This gives better overall DPS than the Damage Tree for most situations, especially in late-game Infinite mode.
How does Spiral Power work?
Spiral Power accumulates based on damage dealt: [Damage ÷ 100,000,000] per wave, capped at 1000. Every 100 SP gives +2.5% range (max +50%). At 500 SP you gain "Exposed", at 750 SP you gain "Negation", and at 1000 SP you unlock Enhanced Dismantle (2.28× damage DoT with HP drain). It's a permanent scaling mechanic that makes Shimon stronger the longer he fights.
Can I pilot the Tengen Toppa Lagann mech?
Yes! Players can manually pilot the mech for enhanced control. When you pilot, you get 0.5-1% current HP damage on attacks. When the character pilots automatically, you get 2-2.5% HP damage (uncapped). The manual piloting adds skill expression and allows you to optimize positioning and timing for maximum damage output.
Shimon vs Rimuru (True Dragon God)?
Rimuru is stronger overall (SS-tier vs S-tier). Rimuru has 30.8M DPS vs Shimon's 74.3M DPS at max, but Rimuru's complex skill system and infinite scaling give him the edge. However, Shimon is easier to obtain (Halloween event vs Coronation grind), more fun to play (pilotable mech), and excels specifically in Infinite mode with HP% damage. Both are worth getting if possible.
