Aubrey's Cellphone somehow survived its trip to limbo with Aubrey herself. Once a day, Aubrey must roll a d20, on a 5 or below, the cellphone is at low battery, and she must roll all abilities of the phone at disadvantage. A natural 1 on any of those disadvantage rolls kills the phones battery, and it's magic is forever gone. Along with the normal features of a cell phone (model is Tiff's choice), the phone appears to have gained the following abilities:
Comprehend Languages (3 charges, lasts 1 hour) [Translate]
Storage Can hold up to one spell as a spell slot, allowing spellcasters to store a backup spell. If the Cellstone loses power or is destroyed, the stored spell is lost.
Teleport Beacon Once a day, the phone can be activated to mark a location, allowing the user to teleport back to that spot later.
Illusionary Disguise Twice per short rest, the user can use the phone to create illusory disguises, altering their appearance temporarily.
Notes: Owner must set a PIN that can be broken with DC 15 INT & Sleight of Hand checks, Communication
