Support

Beyond your units, two systems round out your castle. Helpers are battle abilities you fire for extra pressure or defense, and wheels change how your castle moves. Both are optional, both level up to 5, and both unlock as you climb arenas and raise your forge level.

For when to bring which helper, see Winning a battle.

Wheels

Wheels give the castle its mobility and a small stat lean. Higher Speed, Power, and Fuel factors mean a wheel that rolls faster, hits harder, and lasts longer.

Hover leads on speed at ×1.3. Most wheels unlock through the forge, so leveling the forge opens your options here.
