I'm currently playing a level 6 warlock (pact of the seeker) in a campaign right now. I want to develop a new spell in game. This is the spell that I'm trying to create:
Name: Xanlin's Secret Bookshelf
Level: 4th level conjuration
Casting Time: 1 action
Components: V S M (An exquisite bookshelf, 4 feet tall by 3 feet wide by 1 foot deep, constructed from rare materials worth at least 5,000 gp, and a Tiny replica made from the same materials worth at least 50 gp)
You hide a bookshelf, and all its contents, on the Ethereal Plane. You must touch the bookshelf and the miniature replica that serves as a material component for the spell. The bookshelf can contain up to 25 books or scrolls of varying sizes.
While the bookshelf remains on the Ethereal Plane, you can use an action and touch the replica to recall the bookshelf. It appears in an unoccupied space on the ground within 5 feet of you. You can send the bookshelf back to the Ethereal Plane by using an action and touching both the bookshelf and the replica.
I have two questions for this:
- Is this spell balanced? If not, what changes would you recommend?
- Are there any rules for a player creating a spell in game? I'm vaguely aware of the rules in the DMG for DMs creating spell, but are there any for players? If not, are there any places I can look to for guidance?
I based this spell off of Leomund's Tiny Chest with minor modifications. IT doesn't expire, but I figured that since you can only store books/scrolls and not treasure that is fine balance-wise.
