Custom Ioun Stone


Homebrew and House Rules


It came up in another thread as sort of a threadjack.

How would you price the Rings of Spellstoring or the Ioun stone that mimics the effects?

They use "Imbue with Spell Ability"for a requirement which is a 4th level Cleric spell.

The minor ring is 3 levels for 18k, the "normal" one is 5 levels for 50k and the "major" one is 10 levels for 200k.

The Ioun stone is 3 levels for 30k.

Creation guide says to double the cost for a slotless item.. but
18k*2 is 32k not 30k.

I know that they do modify the cost based on what should be available for the level but for determing say.. 1 level rather than 3, or maybe 2 or 4 or 6. what do you think the equation would be?

Math is not my subject. but I figured maybe one of you for whom it is a fun subject could lend a hand? :)

(This is totally aside from the issue on whether or not a DM *should* allow a PC to deviate from the said printed items.. especially as I suspect a "One level" item would be very very cheap before "DM Adjustment")

Without going into complicated maths (since you aren't a math person), you can easily just double it and round down to the nearest 10k. Since double the price of the minor ring is actually 36k, it's easier than the complicated maths needed to do that.

So, "normal" ioun stone would be 100k and the greater would be 200k. By the time you can afford to spend 100 or 200k on sundry magic items, five or ten thousand this way or that isn't going to be a big deal. It also makes spending it easier since you don't end up with odd sums.


It also looks like a ring with N levels costs N^2 * 2k gp.

The slotless item looks like they doubled and rounded down to get a simpler number.


thanks for the input. I don't mind rounding it just makes it harder for math idiots like me to figure it all out lol :)

so (level squared)*2 for the ring, and double that all again for the ioun stone?

so 4k for the 1 ring, 8k for 2 levels, and so on?

Yes.

1-level: Ring 2k, Ioun Stone 4k
3-level: Ring 18k, Ioun Stone 36k [30k in book]
5-level: Ring 50k, Ioun Stone 100k
7-level: Ring 98k, Ioun Stone 196k
10-level: Ring 200k, Ioun Stone 400k


Thanks much!
