Is an part of a special event where there is a easy, medium, and hard mode.
- Darkmount (medium)
- Blitzwing (medium)
- Sky shadow (easy)
- Power Tokens
- Dinobots (Dinobots destruction only)
- Drop Tokens (Very, very rarely, on hard only)
Each mode there is multiple maps. But on easy there is 3 maps, medium 4, hard 5. If one of your characters dies in battle, that character cannot fight again on a stronghold unless your on a different map, play normal, reset the map, or complete the map.
