Runestones are required to enter a Fortress floor level. They can be obtained through levelling up slides from your Registry or through the in-game store.
Runestones can have various levels. The higher the Runestone you use to enter a floor level of a Fortress, the greater the difficulty of said floor. The rewards from completion of the floor will also depend on the Runestone level AND the Registry to which the Runestone is associated with. Below are the rewards we are currently aware of.
- Runestone level 1: Base Reward of 4 Challenge Fragments + 1 bonus Fragment
- Runestone level 2: Base Reward of 4 Challenge Fragments + 2 bonus Fragments (1.5x bonus)
- Runestone level 3: Base Reward of 4 Challenge Fragments + 4 bonus Fragments (2.0x bonus)
- Runestone level 4: Base Reward of 4 Challenge Fragments + 6 bonus Fragments (2.5x bonus)
