What beats what

Flyer — only 🏹 Scout Tower and ❄️ Frost Tower can hit it. A maze full of ground-only cannons is a free win for flyers.
Runner — high fire rate beats high damage, since every individual shot has a 25% chance to miss.
Tank — its 15% reflect punishes glass-cannon towers; slow it and burn it down with sustained fire.
Healer — kill it first or your chip damage does nothing.
Splitter — splash damage handles the halves; single-target fire drowns.
Brute — it stops at your towers, so keep repairs funded and shield the front line.
Boss — the shield cycles on and off, so save spells for the gaps.
