Antaraxes' Necklace of Spell Storing

Antaraxes' Necklace of Spell Storing
Wondrous Item, Artifact (requires attunement)

This necklace is ornately made, with a fine gold chain supporting a brooch of gold in the shape of a coiled dragon, with a multi-faceted ruby set in the center of the brooch. There are dragon runes inscribed on the reverse of the brooch. These reference the special powers of the item, and must be brushed to activate the power while speaking the command word (dragon rune).

The necklace can store spells cast into it, holding them until the attuned wearer uses them. Unlike the ring of similar name, the necklace can store up to five spells at one time, rather than five levels of spell, to a maximum of 15 spell levels total. The dragon magic allows it to contain the extra energy. When discovered, the necklace may contain 1d4-1 spells of level two or lower.

Any creature can cast a spell into the necklace by touching the ruby when the spell is cast. The spell has no effect, other than to be stored in the necklace. If the necklace is unable to hold the spell, it is expended without effect. The level of the slot used in casting the spell determines how much space it takes in the necklace.

While wearing the necklace, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the necklace is no longer stored in it, freeing up whatever space it had occupied.

Major Beneficial Property: Once per day, while attuned to the item, the holder can attempt to use the power of the necklace to capture a spell cast at its wearer. If the wearer uses this power against a targeted spell, the wearer makes a saving throw against the spell DC of the caster. If successful, the spell is stored in the necklace as any other spell, taking up space in the same way as mentioned above. If they fail on the saving throw, they take double the effect of the spell. If the spell requires a saving throw as cast, the wearer makes their saving throw to capture the spell with advantage, taking no damage on a success as they store the spell in the necklace, or double the effect of the spell on a failure. The necklace can only store one captured spell at a time, and the wearer must use the captured spell prior to attempting to capture another.

Destroying the Necklace: The necklace can be destroyed by the touch of its creator, Antaraxes Glavenis, the adult red dragon, while in its lair at Scarred Peak.
