Storm Mages and Thunder Knights build static charge with every attack — on the 10th hit they unleash a Lightning Surge that stuns the target for 1.5 seconds! Stunned enemies take extra damage from follow-up attacks. Place these units at chokepoints where enemies clump for maximum chain-stun opportunities. Each stunned kill earns +11G bonus!
Where: Build ▸ Lightning Surge
Druids and Rangers channel nature energy every 9 seconds — releasing a 5-thorn cone burst that fans out across the path! Each thorn pierces independently so dense groups take multiple hits.

The traps work automatically so this unit ability is great on shorter paths where enemies cluster.
Where: Build ▸ Crystal Spike
Volcano Mages and Ember Sages conjure and launch a molten lava ball every 13 seconds — when it lands it explodes in a burst of lava, then leaves a burning ground tile that continues scorching any enemy that walks through it for 3 full seconds!

Every single enemy caught in the spin takes heavy damage simultaneously. This is peak crowd-control damage: position whirlwind units at the narrowest path chokepoints where enemy density is highest. The spin hits at the same moment, so it's great for finishing off weakened packs. +13G per slash kill!
Where: Build ▸ Whirlwind Slash
Druids and Nature Callers are masters of terrain control — every 13 seconds they shoot out explosive root tendrils that burst from the ground and COMPLETELY IMMOBILIZE a target enemy for 3 full seconds! The snared enemy can't move an inch. While immobilized your towers pour uninterrupted damage into a stationary target — tripling effective DPS on the snaree. The root snare prioritizes the highest-HP enemy automatically. Each snare kill earns +11G nature bonus!
Where: Build ▸ Root Snare
Demolishers and Siege Bombers forge chain bombs — explosive devices connected by detonation fuses! Every 14 seconds they lob a chain bomb that bounces to 3 different enemies in sequence, triggering a small explosion on each! One throw = three hits.

Position your bombers behind your front line for maximum bounce coverage!
Where: Build ▸ Chain Bomb
Ghost Archers and Phantom Rangers fire arrows made of pure ectoplasmic energy — arrows that pass through solid matter entirely! Every 10 seconds they loose a spectral arrow that travels in a straight line hitting EVERY single enemy standing in that lane simultaneously! One shot can defeat an entire column. Line attacks are most devastating when enemies bunch up — position archers at the start of straight path sections for maximum piercing coverage. Each spectral kill earns +15G ethereal bonus. Essential against dense formations!
Where: Build ▸ Spectral Arrow
Storm Callers and Tempest Mages summon concentrated lightning storms from above — every 12 seconds a violent storm manifests directly over the path, unleashing 3 rapid lightning strikes that hit independent targets simultaneously! Unlike single-bolt lightning, the storm spreads damage across multiple enemies at once, making it exceptional against grouped waves. Each strike earns +13G electrocution bonus. Storm Callers are especially devastating against tight column formations where the 3 strikes can each hit a different enemy in the same cluster for triple kills in a single cast!
Where: Build ▸ Storm Caller
