Challenges

Challenges are missions that deviate from the standard gameplay rules of Campaign.

There are 13 challenges (19 on PC and more in Redux) that do not require any DLC to play. A list of all bonus DLC challenges can be found here.

List of Original Challenges[]

Assault	Endless Spires	Players must destroy all enemy cores within the time limit. No defenses can be summoned, and heroes are handicapped.

Monster Fest	Glitterhelm Caverns	There are no crystals to defend, but each wave must be completed within its time limit.

These challenges were added in free CDT content updates. They can be found under "The Lost Quests" tab.

Challenge	Map	Summary
Pirate Invasion	Buccaneer Bay	An endless survival challenge. Yields more mana and pirate accessories the longer players survive. Losing after wave 7 counts as a victory.
Flames of Rebirth	Embermount Volcano	The young Phoenix must be defeated multiple times during the waves before it regains its "true power."
Temple of Polybius	Temple of Water	A difficult three-part challenge consisting of an assault, core defense and boss gauntlet.
Crystalline Resurgence: Part 4	Crystalline Dimension (Field 4)	Boss monsters spawn on every wave which must be killed to complete each wave. The Genie King on the last wave is immune to generic/physical damage.
Crystal Escort: Spring Valley	Spring Valley	Players must escort an Easter Egg Basket back to the castle while defending it against hordes of enemies. This Eternia Crystal is essentially invincible, until the final wave.
Tomb of Etheria	Tomb of Etheria	Boss monsters are fought outside the tomb over the first three waves, during which no defenses can be summoned. Inside the tomb, more enemy pathways to the crystals open as players progress.

No challenge-exclusive map (ex: Temple O' Love, Silent Night, Tomb of Etheria) has a Survival or Pure Strategy mode available after completion.

Most challenge missions give far less experience points than Campaign or Survival missions.
