Your Cannon now channels lightning — each shot has a 25% chance to CHAIN to up to 3 nearby enemies at 70% power! Chain kills earn +5G per bounce (up to +15G per proc). Position Cannon where enemies cluster to maximize chain bounces and gold income!
Where: Build ▸ Thunder Strike
These undead constructs regenerate 8 HP every second — they can outlast weaker towers! Deal 30+ damage in a SINGLE HIT to interrupt their regen for +15G interrupt kill. Fire mages counter them best: fire damage bypasses their physical resistance and deals burst hits that break regen!
Where: Fight ▸ Bone Constructs
Gravity Worms create powerful gravity traps that pull nearby enemies into kill zones! Any enemy caught in a gravity trap earns +17G on kill. Use Archers to counter — they pierce gravity fields that slow most projectiles. 3 types scale from gravel to singularity class!
Where: Fight ▸ Gravity Worms
Shaman and Monk units channel spirit energy over 20 attacks, then release a massive Spirit Bomb — a giant AoE blast hitting everything in a 3-tile radius for massive damage! Each enemy caught in the explosion earns +14G bonus gold. Let the bomb charge fully before engaging dense enemy groups for devastating payouts!
Where: Build ▸ Spirit Bomb
Thunder Mages and Storm Callers channel arc electricity every 10 seconds — releasing a bouncing bolt that leaps from enemy to enemy up to 3 times! Each bounce loses 25% of the previous damage, but hitting multiple enemies at once is incredibly efficient in dense waves. Position arc bolt units near enemy clusters for maximum chain reach. Each chain kill earns +13G bonus gold!
Where: Build ▸ Arc Bolt
Bone Knights are undead warriors that refuse to die — when slain they attempt to reform at 50 HP if not destroyed completely! Holy Mage units deal final-death strikes that prevent reformation. Landing a holy kill earns +20G holy bonus gold. Target the Lich Vanguard variants first — they reform the fastest and lead the charge!
Where: Fight ▸ Bone Knights
Siege Mages and Catapult Sages channel cosmic energy every 20 seconds — then call down a devastating meteor strike on the densest enemy cluster! The impact creates a 3-tile radius explosion that damages everything nearby. Perfect for obliterating tight groups that survived earlier tower fire. Each meteor kill earns +16G bonus gold. The biggest single-hit damage in the game!
Where: Build ▸ Meteor Strike
Magma Elementals are nearly unkillable by conventional means — when they die they explode into 2 smaller elementals that continue marching! The only way to stop the chain reaction is to kill them with Water Mage units. Water kills count as +21G bonus gold AND prevent the split. Three elemental tiers: Cinder Wisp (80HP), Flame Stalker (160HP), and the massive Magma Titan (300HP)!
Where: Fight ▸ Magma Elementals
Phantom Blades and Ghost Swordsmen are battlefield ghosts — every 10 seconds they TELEPORT directly to the furthest enemy on the path and strike it with a devastating blow, completely ignoring all towers and obstacles between them! This makes them the ultimate backline threat, hitting enemies that have somehow made it deep into your kill zone. Each teleport kill earns +14G phantom bonus. Perfect pairing with frontline area units!
Where: Build ▸ Phantom Strike
Chronomancers and Time Sages bend the fabric of time itself — every 18 seconds they unleash a pulsing temporal distortion wave that covers a massive 3-tile radius, slowing ALL enemies inside by 50% for 2 full seconds! This is the largest slow radius in the game. Position them centrally on the path to maximize enemy coverage. During the slow window your other towers deal effectively double damage per second. Each pulse kill earns +12G time bonus!
Where: Build ▸ Time Warp Pulse
Swamp Trolls come equipped with legendary troll regeneration — they heal 2% of their MAX HP every single second while alive! Leave them alive too long and weaker towers can't out-damage their regen. Fire Thrower units however completely neutralize troll biology — the burning chemicals permanently disable regeneration on anything they hit. Each fire-killed troll earns +20G incineration bonus. Three variants: Bog Creeper (120HP), Marsh Bruiser (240HP), and the massive Swamp Titan (480HP)!
Where: Fight ▸ Swamp Trolls
Siege Masters and Artillery Commanders fire a concentrated plasma cannon every 18 seconds creating a massive 5-tile AoE explosion! Each plasma kill earns +16G.
Where: Build ▸ Plasma Cannon
Rogue Captains and Shadow Scouts deploy a 5-second smoke screen every 20s causing enemies inside to miss 30% of attacks — they flail blindly! +12G/kill.
Where: Build ▸ Smoke Screen
Forge Knights and Lava Wardens create a lava moat across the path every 18s lasting 4s — enemies crossing it are slowed to 40% speed! Great for stacking tower damage. +13G/kill.
Where: Build ▸ Lava Moat

Where: Build ▸ Decay Pulse
Frost Archers and Ice Knights shatter ice shards every 10s slowing hit enemies by 50% for 3s — time your waves to maximise the slowdown window. +14G/kill.
Where: Build ▸ Ice Shards

Where: Build ▸ Lightning Hammer
Pyro Cyclone units spawn spinning flame vortexes that travel across the battlefield dealing tick damage to every enemy they touch — set and forget. +13G/kill.
Where: Build ▸ Flame Tornado
Venomancers summon corrosive clouds every 14s that strip 20% armor from every enemy inside — this makes all other damage sources hit harder simultaneously. +13G/kill.
Where: Build ▸ Poison Storm
Frost Sages hurl a massive ice comet every 15s that explodes on impact creating a 90px frost zone. Enemies walking through the zone are slowed 40% for 6s — great for chokepoints. +13G/kill.
