Arcane Arsenal

You store up to four spell levels (maximum of two spells) into a precious gem for later activation.

For example, you could store two 2nd level spells, a1st level spell and a 3rd level spell or one 4th-level spell.

Whenever spells are stored in the gem it leaves a faint glow that sheds bright light in a 5-foot radius and dim light for an additional 10 feet.

As an action, you can unleash the arsenal at a single target of your choosing using the smallest range type of the stored spells.

Both Arcane Arsenal (unless it is cast as a ritual) and the triggered spells must be prepared.

Treat non-scalable cantrips as one spell level otherwise count them as two spell levels.

If multiple concentration spells are activated their immediate effect take place on that turn and the wizard must choose which spell (if any) to maintain concentration.

The arsenal lasts until activated or the containing item is destroyed.

A wizard can possess only one Arcane Arsenal at a time, and it may not be activated by other characters.

As a bonus action, any arcane magic user can touch the Arsenal and absorb half of the stored spell levels to restore slots no higher than level four.

At Higher Levels

For every two levels above 4th, you can store an additional two spell levels and add +1 to the spell maximum.

At 6th level, you can store up to three spells, with a cumulative six spell levels.

At 8th level, you can store up to four spells, with a cumulative eight spell levels.
