Azura’s Star

This unique trinket is a haphazardly interconnected structure of purplish crystals loosely shaped like a star. It appears to have once been worn as an amulet, maybe affixed atop a staff.

When first attuning to Azura’s Star, the artifact weighs the heart of the creature trying to attune to it. If determined to be Good, Azura’s Star becomes a light purple and takes on the traits of the Bright Star. If determined to be Evil, Azura’s Star becomes an inky purple and takes on the traits of the Dark Star. If the alignment of the character attuned to it changes, they are no longer attuned to Azura’s Star and cannot re-attune for 1d10 years.

Bright Star: Has the ability to trap the souls of non-humanoids. Whenever the wielder kills a non-humanoid creature (excluding constructs and the undead), you may attempt to trap the soul of the creature, rolling a DC 19 Arcana check. On a success, the soul is trapped in the Star, adding 1 charge.

Dark Star: Has the ability to trap the souls of humanoids. Whenever the wielder kills a sentient humanoid creature (excluding constructs and the undead), you may attempt to trap the soul of the creature, rolling a DC 23 Arcana check. On a success, the soul is trapped in the Star, adding 2 charges.

Soul Charged. The charges may be spent to switch prepared spells, refill spell slots, or fulfill component costs. The Star may be used once per turn as an action, and only one affect per action (eg. you can't restore a spell slot and substitute component costs to cast the spell in the same turn). The Star can store an unlimited amount of souls indefinitely. The charges may be spent in the following ways:

• Partially or fully substitute the component costs of any spell (as defined in the spell's description), expending 1 charge per 100 GP
• Restore spell slots, costing 1 charge per spell level
• Change a single prepared spell for the day, costing 1 charge per spell level. Cantrips cost 1 charge

Azura’s Star acts as a +3 Arcane Focus.
