Element strengths & weaknesses

Hybrid enemies: none on maps 1–2, approximately 20% on maps 3–5, and 35% on maps 6–10. They replace normal enemies and have the same HP and speed. Damage averages both defending elements. Hybrid tower attacks average all four pairings. Bosses remain normal elements. Hybrid enemies currently use hybrid icons as temporary artwork.

Item catalog

5% item drop chance per kill. Drops are Normal, equally selected from 20 types. Combine 3 matching Normal items from Bag or equipped towers into Rare, or 3 matching Rare into Epic: 100% success, no coin cost. Six equipment slots; one of each item type across all rarities. Different projectile items (16–20) can be equipped together within six slots. Each activates independently from the main attack; extra shots never split again. Extra projectiles cannot critically hit or trigger Midas, item or branch effects. Crosswind extra attacks do not activate projectile items.

    Inside a Gold Vulnerability aura, takes 1% more damage per Gold level (maximum 10%). Broken shield shows −1% to −10%. Strongest bonus with Fracture only; ends immediately outside aura.

  • ♢ Fracture

    Takes increased damage from all sources.

Small badges above the health bar show current effects. They disappear when the effect expires or is consumed. Different effects may appear together.

Silver rocks · blocked build tiles
Rocks block building

Silver rocks occupy grid tiles. You cannot build or redeploy a returned tower on a rock.

More rocks every 5 waves

Clearing waves 5 and 10 adds two rocks to free build tiles. Rocks never replace towers or block the enemy path.

Rock totals carry forward

The next map starts with the same total number of silver rocks, placed on free tiles in its new layout. New rocks keep adding to that total. A new campaign starts at zero.

Boss suppression

Bosses move at 80% of normal monster speed and have 10% armor reduction against all damage, after elemental multipliers. Normal monsters have no armor.

Bosses move at 80% of normal monster speed and have 10% armor reduction against all damage, after elemental multipliers. Normal monsters have no armor.

Recognize the boss

Bosses have a glowing halo and a BOSS label. They are slow, have 12× normal health, and cost 5 lives if they escape.

Boss wave

A boss joins wave 10 on each 10-wave map and arrives after the normal enemies. The boss spawn count continues across all ten maps.

Each boss suppresses more towers

Boss #1 suppresses 1 random tower, boss #2 suppresses 2, up to 10. If fewer towers exist, all are suppressed. New towers can be affected until the quota is filled.

Tower damage −40% · Gold aura −20%

A 40↓ badge marks suppressed attacking towers: direct, splash, burn and field damage retain 60% strength. Gold towers show 20↓: their range or fire-rate aura retains 80% strength. Gold aura radius and other Gold skills stay unchanged. Attack speed, control duration and coin income otherwise stay unchanged.

Recovery

All suppressed towers return to normal when the entire boss wave ends, even if the boss died earlier. A new campaign resets the boss count to zero.

Coins, loot & equipment
Keep Towers bonus

At every map clear, Keep Towers retains levels, skills and equipped cores and grants 10% of tower building plus upgrade costs as coins, rounded down. Items return to Bag. Bonus is paid once when starting the next map; after map 10, it carries into the next campaign. Cores/items do not add coin value.

Earn coins

Normal kills pay 4 coins on map 1, +1 per map (13 on map 10). Boss kills pay 80 × map number (80–800 coins). Wave bonuses and 10% interest are unchanged.

Coin drops · 1% per kill

Any kill, including a boss, has a 1% chance to drop a coin on the map. Tap the coin to collect it during combat. Uncollected coin drops are collected automatically when the wave ends, before interest and map-clear rewards.

Item drops · 5% per kill

Items go straight to Bag. Each attacking tower has six equipment slots and can equip only one of each item. Gold support towers cannot equip items.

Equip and remove

Select a tower → Equipment opens Bag. Tap an item to equip it. Tap a filled slot to put the item back in Bag.

Sell or clear

Selling refunds half of tower and upgrade spending. Equipped items always return to Bag when selling or clearing a map.

Tower roles
Water

Slows enemies. Its water spirit ripples and bobs, then leans forward to cast.

Fire

The flame spirit lunges and releases an animated fireball with a flame tail, sparks and an impact burst. All character and projectile animations are visual only. Animation stops when paused or boss-disabled.

Earth

Heavy damage, slower shots. Its rocky spirit rocks gently and has a heavier casting recoil.

Air

Fast attacks. Its cloud spirit floats with swirling wisps and casts with a quick gust pulse.

Lightning

Applies shock so another tower can deal bonus damage. Its electric spirit crackles and flashes as it casts.

Gold support

Choose a range or fire-rate aura. The Gold spirit sparkles and pulses its aura instead of attacking. Only the strongest covering bonus in each aura category applies. Boss-paused Gold towers give no aura.

Gold chooses one aura: Range, Attack Speed, or Vulnerability. Vulnerability makes enemies inside its radius take +1% damage per level, up to +10%. Strongest Vulnerability or Fracture applies; Gold suppression reduces aura strength by 20%.

Hybrid tower roles

Equip one different elemental core to an attacking tower. Both mixing orders give identical hybrid stats. Hybrid skills replace the original skills. Choose one branch at level 3; it improves at levels 6 and 10.

  • Steam: Area damage and slowing.
  • Magma: Burning ground and explosions.
  • Firestorm: Crowd damage and spreading burn.
  • Plasma: Focused damage against tough enemies.
  • Mud: Slowing, rooting and weakening enemies.
  • Frost: Freezing and crowd control.
  • Storm: Chain damage and marks that amplify another tower’s hit.
  • Sandstorm: Area damage, weakening and slowing.
  • Magnet: Damage marks, slowing and piercing shots.
  • Thunder: Fast attacks, stuns and piercing shots.
