Five elements
Heroes combine Burning, Lightning, Frost, Energy, and Physical tags. Team synergies activate when elements complement — Burning with meteor area skills, Frost with slow towers, Lightning with chain burst, Energy with EMP structures, Physical with fortress walls.
Match elements across heroes, roguelike picks, and buildings instead of mixing randomly. The best team page lists templates.
Burning and Lightning burst
Burning carries like Cole and Emily pair with Fire structures and Arena lineups tested in community videos. Lightning from Bell and Aula loves grouped enemies under freeze.
See Arena guide for Fire lineup notes.
Frost and Energy control
Frost from Mir slows waves for Machine Gun uptime. Energy from Rex amplifies EMP towers. Control-first synergies stabilize campaign before burst investments.
