Wilderness - Proving Grounds is a stage in Shovel Knight Showdown. It's unlocked by seeing 20 different modes in Chester's Choice.
This stage is based on the field where Phantom Striker confronts Shovel Knight and Plague Knight in Shovel Of Hope and Plague Of Shadows. This stage loops around on the sides. The main gimmick of this stage is the heavy wind that blows periodically, like the wind that blows during battles against Phantom Striker in the original campaigns.
