This mysterious and powerful stone is a recent invention thanks to a collaboration between House Cannith and House Jorasco. Its creation process and origins are currently kept in secret, but there are hints of unstable Dragonmark magic in its make. To use the stone, it must be activated through a ritual and then roll an Intelligence (Arcana) check.

• At a successful DC 13 roll, up to a number of 8 humanoids within 5 feet of you (including yourself) all get the benefits of a long rest.
• On a failure, you all instead get the benefits of a short rest and restore one spell slot for each level up to 5th-level, if any. You also restore half the amount of resources spent for any class or race feature or feat that you have that would normally require a long rest, such as a Fighter's Indomitable feature or a Shifter's Shifting feature.
• If you roll a 1 on the d20, the Aberrant Stone becomes unstable and bursts into an arcane implosion and is destroyed. You all also lose half the number of your total Hit Dice, and which could only be restored after a long rest.

After activating the stone, whether success or failure, it cannot be used for 7 days.
