A dramatic comeback mechanic!

Storm Wraiths are spectral fliers with a 40% dodge chance — nearly half your shots miss them completely! However, Wind Archer units fire homing arrows that pierce through the dodge field. Each Wind Archer kill earns +22G dodge bonus. Position them early since Cyclone Reapers move at triple speed and can outrun non-archer defenses!
Where: Fight ▸ Storm Wraiths
Crystal Golems are living mirrors — every hit bounces 20% of your towers' own damage back at them! Fire weak rapid-fire attacks rather than slow heavy cannons to minimize reflected damage. Acid Cannon units bypass the reflective hide entirely and shred golems without the ricochet risk. Three golem variants: Quartz Shard (120HP), Gem Titan (240HP), and the towering Prismatic Colossus (460HP)!
Where: Fight ▸ Crystal Golems
Frost Wraiths are COMPLETELY immune to fire damage — fire towers deal literally zero damage to them! Your standard defenses are useless.

Three wraith variants: Chill Shade (90HP), Blizzard Specter (190HP), and the terrifying Glacial Phantom (370HP)!
Where: Fight ▸ Frost Wraiths
Cursed Scarecrows don't attack directly — instead each one that stays alive on the path emits a dark curse aura that reduces ALL your tower damage by 30%!

Three variants: Hay Haunter (95HP), Dread Effigy (200HP), and the massive Hex Colossus (400HP)!
Where: Fight ▸ Cursed Scarecrows
Frost Fiends carry cores of absolute zero temperature — the very first attack they absorb FREEZES the attacking tower solid for 1 full second! Your offense briefly stops the moment it engages one. Flame Ward units constantly burn hot enough to melt the frost core before it triggers, completely nullifying the freeze. Each flame kill earns +20G fire bonus. Three variants of escalating menace: Ice Imp (85HP), Frost Ghoul (175HP), and the devastating Glacial Demon (350HP)!
Where: Fight ▸ Frost Fiends
Thunder Wraiths are spectral lightning entities with a dangerous reactive defense — the very first tower that successfully hits a Thunder Wraith gets stunned by a retaliatory lightning bolt for 1.5 full seconds! Your fastest towers will be silenced the moment they engage. Ground Rod units are properly grounded and immune to the stun retaliation — they can safely attack wraiths without being shocked back. Each grounded kill earns +21G lightning rod bonus. Three stormy forms: Spark Shade (95HP), Storm Specter (190HP), and Thunder Banshee (380HP)!
Where: Fight ▸ Thunder Wraiths
Spirit Warriors are partially phased into the spirit realm, making them physically intangible — physical projectiles like arrows, bolts, and cannon balls pass straight through their ethereal bodies without effect! Only magic-based towers that project magical energy can harm them. This forces you to invest in magic towers specifically for spirit warrior waves. Spirit Seal units project magical binding circles that anchor spirit warriors to the physical plane, making them temporarily vulnerable to all damage types. Each seal kill earns +22G binding bonus. Three spectral forms: Ghost Soldier (105HP), Specter Knight (210HP), Phantom Warlord (420HP)!
Where: Fight ▸ Spirit Warriors
Bone Archers are undead marksmen that fire cursed arrows which don't simply deal damage — they drain health directly from your units, transferring stolen life force back into the bone archers themselves to regenerate. The more units they hit, the more they heal. Shield Bearer units physically block bone arrow volleys with massive shields, absorbing all arrow damage before it reaches your vulnerable towers and dealing crushing counter-strikes. Each shield block earns +28G deflection bonus. Three bone-tier variants: Skeleton Archer (95HP), Bone Sniper (190HP), Ancient Marksman (380HP)!
Where: Fight ▸ Bone Archers
Soul Warriors hurl spectral lances every 8s that pierce through 3 enemies dealing 55 damage each. +16G/kill.
