An Aurorasite can contain one spell from any class’s spell list, passive buffs, or effects. You become aware of the effect when you divine the gems nature. While holding the gem, you can cast the spell from it as an action. Doing so doesn’t require any components and doesn’t require attunement. The gem can be used in this way once per day, or by using a spell slot.
If the spell is of a higher level than you can normally cast, you must make an ability check using your spellcasting ability to determine whether you cast it successfully. The DC equals 13 + the spell’s level. On a failed check, the spell fades from the crystal with no other effect.
Each Aurorasite has a maximum level for the spell it can contain. The spell level determines the gem’s rarity and the stored spell’s saving throw DC and attack bonus, as shown in the Aurorasite table. Only through compounding a gem can it be upgraded to cast higher level spells.
The raw Aurorasite is an uncommon item and can contain a cantrip. The stored spell's saving throw DC is 11 and has a +3 attack bonus.
