Best Towers for Frost Mode

S-Tier (Must Have)

Tower	Level	Why It’s Essential
Accelerator	4+	Full map coverage, insane DPS
Ducky	Max	High sustained damage
TZ (Turret Zone)	Max	Excellent crowd control

A-Tier (Highly Recommended)

Tower	Level	Role
Toxic Gunner	3+	Early wave swarm clear
Commander	Max	Buff nearby towers
DDS	Max	Crowd control support

Towers to AVOID

Tower	Why
Medic	Gets frozen, doesn’t protect from freeze

Best Team Composition

For the ideal Frost Mode setup, aim for:

1. 5x Maxed Accelerators - Your main DPS
2. 2-3x Maxed Ducky - Secondary damage
3. 2-3x Maxed TZ - Crowd control
4. 5x Level 3 Toxic Gunners - Early game starters

This composition can clear Frost Mode solo with proper placement.

Wave-by-Wave Strategy

Early Game (Waves 1-10)

1. Start with $1,000 and immediately place 5x Level 3 Toxic Gunners
2. These handle frozen enemy swarms in early waves
3. Start saving for Accelerators
4. Position towers for maximum path coverage

Mid Game (Waves 11-25)

1. Upgrade to maxed Accelerators (L4+ for full map coverage)
2. Add Duckies and TZs for support
3. Wave 15 Boss: Fast 300+ HP enemy that stuns towers on contact
   • Counter with heavy DPS ramp-up before it spawns
4. Use supply drops and beacons effectively

Late Game (Waves 26-40)

1. Max out all key towers before final waves
2. Handle Acolyte and Frost Heroes with sustained DPS
3. Watch for spike waves (Wave 39 especially)
4. Prepare for final boss

Boss Mechanics

Wave 15 Boss

• Stats: 300+ HP, very fast
• Mechanic: Stuns towers on contact
• Counter: Heavy DPS ramp-up with Accelerators and TZs

Mid-Game Frost Heroes

• Stats: High speed and health
• Mechanic: Explode when unstabilized ice is destroyed
• Counter: Max coverage towers to shred them quickly

Final Boss (Wave 40)

• Mechanics:
  • Summons beacons and nukes
  • Freezes EVERYTHING (even stun-immune towers)
  • Spawns chill enemies
• Counter:
  • Stack all DPS before it spawns
  • Nuke it immediately when it appears
  • Avoid chill enemies

Grinding Tips

Maximum Snowmen Grinding

• Use modifiers to boost rewards
• Repeat runs for consistent drops
• Quad servers help reach Triumph faster

Coin Efficiency

• Use coin-boosting modifiers
• Clear waves quickly for faster runs
• Focus on Triumph for 75 gem bonus

Common Mistakes to Avoid

1. Using Medic towers - They freeze and don’t protect others
2. Spreading towers too thin - Concentrate firepower on key chokepoints
3. Ignoring Wave 15 - This boss catches many players off guard
4. Not preparing for Wave 40 - Stack DPS BEFORE the final boss spawns
5. Skipping Toxic Gunners early - Cheap swarm clear is essential

Quick Reference

Wave	Threat	Preparation
1-10	Swarms	5x L3 Toxic Gunners
15	Fast Boss	Max Accelerators
26-38	Frost Heroes	Full tower coverage
39	Spike Wave	All towers maxed
40	Final Boss	Stack DPS, nuke immediately

Conclusion

Frost Mode is one of the best ways to grind both coins and event currency during the Winter Event 2025. With the right tower setup (Accelerators, Ducky, TZ) and proper wave preparation, you can achieve Triumph and earn those 75 gems along with legendary drop chances.
