Read each boss before it strikes
The map preview now updates the homepage colors and shows the local enemies, towers and boss. In battle, the warning names the skill and explains what it can affect.

Take a different action on each map
In Pinewatch, Ancient Hart charges toward the lighthouse. Keep control and firepower near the later bends. On Frostglass Shore, the howl delays tower fire. Keep a second firing group outside its warning area. In Sporewood, focus the weakened enemies before the Regent heals them.
Restart from wave one
After returning to the game, use Restart from wave 1 in the pause or checkpoint screen to start fresh with that map, hero and difficulty. Continue keeps the existing defense.
