The Inferno Hydra has 3 separate heads — each one you destroy triggers a phase change, making the boss attack differently! Fire-resistant counters will fail as it changes tactics. Use Frost Archer units to freeze the fire heads mid-phase. Defeating each head earns +40G — maximum payout if you can handle all 3!

Poison Elementals trail toxic clouds that stack up around them — the longer they live, the denser the poison in a 2-tile radius!

Where: Fight ▸ Poison Elementals

Keep your magic defenses ready!
Where: Fight ▸ Thunder Drakes
Void Crawlers don't use the road — they travel diagonally, cutting across open terrain and bypassing your carefully placed chokepoints entirely! Most towers are built to cover road tiles and can't hit off-road targets. Spider Trap units are the solution: they extend coverage beyond the road and intercept diagonal movements. Each crawler caught by a trap earns +23G interception gold. Shadow Crawler (100HP) → Abyss Stalker (380HP)!
Where: Fight ▸ Void Crawlers
Bone Colossi are nightmarish undead tanks with a unique property: they are COMPLETELY IMMUNE to all slow effects! Your freeze towers, web traps, and ice spells do absolutely nothing to them. Only raw damage kills them. Earth Shaker units however can briefly stagger them with ground-shaking impacts, breaking their immunity for a window. Each stagger kill earns +20G. Three sizes: Bone Strider (130HP), Marrow Giant (260HP), and Ossified Titan (500HP)!

Multiple Plague Lords stack infection, potentially slowing your entire defense to a crawl. Cure Altar units have developed an antidote that instantly cleanses infected towers and poisons Plague Lords on contact. Each cured kill earns +23G antidote bonus. Three rotting variants: Blight Priest (135HP), Pestilence Lord (270HP), and Plague Herald (540HP)!
Where: Fight ▸ Plague Lords
Soul Leeches are parasitic spectral entities that feed on the energy of your castle's treasury — every round a Soul Leech survives on the path, it siphons 5 gold from your income! Multiple leeches stack their drain, crippling your economy one gold at a time. Holy Flame units carry sacred fire that burns through the spectral body instantly and restores stolen gold as bonus. Each holy purge earns +26G restoration bonus. Soul Leeches are not the tankiest enemies but their economic damage adds up catastrophically if ignored. Three variants: Wisp Leech (80HP), Soul Devourer (160HP), Void Parasite (320HP)!
Where: Fight ▸ Soul Leeches
Fungal Spores are ambulatory fungal organisms that release clouds of toxic spores continuously as they walk — the spore clouds drift sideways off the path and attach to nearby towers, slowly growing fungal networks that reduce tower attack speed by 30% over 8 seconds! Multiple spores create overlapping cloud zones that can simultaneously infect your entire tower line. Spore Ward units carry specialized chemical sprayers that sterilize spore clouds on contact, removing tower infections and dealing fungal-shock damage. Each ward kill earns +24G cleansing bonus. 3 variants: Spore Cap (100HP), Mycelium Mass (200HP), Ancient Fungus (400HP)!
Where: Fight ▸ Fungal Spores
