Blood Cultists sacrifice 20% of their own HP to buff all nearby enemies with +30% ATK — dangerous if ignored! Kill the Cultist BEFORE it finishes the ritual for an instant preempt bonus of +20G. Prioritize Cultists over regular enemies to disrupt enemy buffs!
Where: Fight ▸ Blood Cultists
These phase-shifting enemies alternate between physical and ethereal planes every 5 seconds! While ethereal, only MAGIC damage can hit them — physical arrows and swords pass right through! Kill them during the 3-second ethereal window for +20G. Deploy mages and archmages to counter these tricky foes!
Where: Fight ▸ Ethereal Walkers
Your Chrono Mage and Time Wizard now freeze TIME itself every 12 shots — all enemies on the battlefield stop completely for 3 full seconds! Kills made during the freeze earn +9G. Position Chrono units where the most enemies cluster for maximum frozen targets each stop!
Where: Build ▸ Time Stop
Iron Golems have thick iron plating that completely blocks all piercing attacks — arrows, spears, and ballista bolts bounce right off! Switch to Mage units casting magic spells to bypass their armor for +22G magic kills. Golems come in 3 sizes: Sentinel, Colossus, and Guardian with increasing HP!
Where: Fight ▸ Iron Golems
Shadow Archers and Echo Mages have mastered the art of echo combat — every 8th attack releases a phantom copy of the strike dealing 50% extra damage! The echo hits the same target a split second later, doubling the damage burst. Chain multiple echo units together for a devastating rapid-fire echo cascade. Each echo kill earns +10G bonus gold!
Where: Build ▸ Phantom Echo
Toxin Mages and Swamp Rangers spray toxic venom every 11 seconds — drenching all enemies in a 2-tile radius with persistent poison! Poisoned enemies take damage over time for several seconds after the spray. Stack multiple venom units for overlapping AoE coverage. Each venom kill earns +12G bonus gold. Perfect for softening dense waves!
Where: Build ▸ Venom Spray
Nova Mages and Arcane Sages release a magical chain nova every 13 seconds — a sphere of energy that bounces from enemy to enemy up to 4 times! Each bounce deals slightly less damage but hits a new target. Dense enemy clusters make the chain nova incredibly efficient. Position nova units at crossroads for maximum chain reach. +12G per chain kill!
Where: Build ▸ Chain Nova
Shadow Walkers and Dark Assassins lurk in the darkness — then every 10 seconds detonate a burst of shadow energy dealing 300% of their normal damage! This is one of the fastest special-ability cooldowns in the game. Each burst kill earns +13G shadow bonus. Position them near chokepoints to maximize burst hits on tightly packed enemies.
Where: Build ▸ Shadow Burst
Arcane Mages and Rune Archers are precision hunters — every 9 seconds they charge and fire a magical homing bolt that automatically seeks the single highest-HP enemy on the entire battlefield! No aim required; the bolt curves to its target and deals heavy damage. Perfect for sniping high-HP bosses and elite variants that have survived your main line of fire. Each bolt kill earns +14G arcane bonus.
Where: Build ▸ Arcane Bolt
Sun Priests and Star Mages channel the power of the sun — every 13 seconds they release a concentrated solar flare that scorches every enemy on the path, reducing their attack speed by 40% for 2 full seconds! This means all enemies slow their attacks during the debuff window, giving your towers breathing room. Layer solar flares with barrier shields for a nearly-invulnerable defense window. Each flare kill earns +12G sun bonus!
Where: Build ▸ Solar Flare
Void Mages and Rift Walkers crack the fabric of reality — every 16 seconds they tear open a swirling void rift that acts as a gravitational singularity! Every enemy within a 2-tile radius gets sucked toward the rift center for 2 full seconds, clumping them tightly together. Then your area-damage towers and splash attacks absolutely devastate the clustered pack. The rift pull stacks with slows — caught enemies can barely move. Each rift kill earns +11G void bonus!
Where: Build ▸ Void Rift
Ice Witches and Frost Sages summon ferocious blizzard cells — every 17 seconds a swirling storm of ice and snow engulfs a 3-tile radius, freezing every enemy solid for 2 full seconds! Frozen enemies can't move or attack, giving your other towers a free firing window every blizzard cycle. Stack multiple blizzard units on the same path segment for overlapping freeze intervals that create near-permanent crowd control. Enemies killed while frozen earn +12G frost bonus!
Where: Build ▸ Blizzard Storm
Geomancers and Earth Mages channel tectonic energy deep underground — every 16 seconds they trigger a localized earthquake that tears through a 4-tile radius! Every enemy caught in the quake zone gets violently knocked back 2 full tiles, disrupting their march and resetting their position! Knockback is incredibly powerful — enemies knocked back far enough can be caught in another field before they even resume walking. Each earthquake kill earns +11G seismic bonus. Combine with chokepoints to keep enemies perpetually stumbling!
Where: Build ▸ Earthquake Field
Astral Mages and Gravity Sages can tap into the fundamental forces of the universe — every 18 seconds they generate a localized gravity well in the center of the path! Every enemy within a 5-tile radius gets pulled toward the gravity well's center simultaneously, compressing widely spread enemies into a single dense cluster. Once clustered, your AoE towers devastate them all at once. The 5-tile pull radius is enormous — it can rearrange entire waves. Each gravity kill earns +12G gravitational bonus. Combine gravity wells with area-damage towers for devastating synergy!
Where: Build ▸ Gravity Well
Druid units and Nature Wardens conjure massive walls of razor-sharp thorns that physically block the enemy path — every 18 seconds they weave living thorn barriers that stand 2 tiles wide across the road! Enemies must stop and hack through the wall, buying your towers precious extra attack time. While enemies are stopped by thorns they take 50% additional damage from all sources. Each thorn kill earns +14G nature bonus. Thorn Walls are most devastating when placed at natural bottlenecks — combine with AoE towers positioned to unload on stopped clusters for maximum devastation!
Where: Build ▸ Thorn Wall
Cryomancers and Ice Mages lob freeze bombs every 16 seconds that flash-freeze a 3-tile radius! Frozen enemies cannot move and take +40% damage from all sources. Each bomb kill earns +15G. Essential against dense waves.
