magic items with charges/week or charges/month

[death390]

so i have been looking into a way to make magic items with charges per week/month/year. so that A its cheaper and B so that some things are more limited, we don't need resurrection more than 1/month (or week if we are bad). some help to try and find a conversion.


we have how to make something last all day (its in the subscript for continuous items (based on time/CL; x4 rnds, x2 min/lvl, x1.5 10min/lvl, /2 if >24hrs)

we have charges/day (# charges/5 times cost)

but we don't have a actual way to do charges/week, month, year. but there are magic items that have some of those charges. bag of tricks, wondrous figurines, ring of the elements, ect.

the only magic items that ONLY have charges/week that i could find were the bag of tricks: grey/rust/tan, at 10 charges/week. (900g/3,000g/6,300g)



since it is a bag of some kind i don't see a component cost to it but possible.
starting with the
Grey bag; 900g. command word item 1800g* 2 * 3 = 10800g for unlimited use of SNA 2. 900*12=10800g
Rust bag: 3,000g: 1800*3*5 = 27,000 SNA 3. 3,000g*9 = 27,000g
tan bag: 6,300g: 1800* 5*9=81000 SNA 5. 6,300g*12.857= 80,999.1

when i was looking at doing this the first time my innitial idea was just to multiply the 5 possible charges per day by 7 resulting in 35 pissible charges per week so x/35 as the multiplier, obviously wrong but is it exactly? just from what i can see from the bags 12 is the magic number (though rust is slightly better valued) so since they have 10 charges it would be 10/120? well if we take everything x3 then its 10*3/360.

so charges*3/360 for weekly charges?




monthly charges we have orb of storms, figurine of wondrous power:ivory goats, and figurine of wondrous power: marble elephant. only the elephant is just monthly charges (4), using animate object (sp6, cl11, rnd/cl) 17,000g.

1800 * 6*11= 118,800g for command use item. obviously not good enough lets x4 to make it a 24hr item; 475,200g.
475,20/ 17,000 = ~27.95 (oh hey its February) the odd bit would be that 4 charges/month and we multiplied that by 4 to make it 24 hour charge. so undo both of those and its 1 charge/28 approximately.

118,800*4/28=`~16,974.43

thoughts?

Please don't forget, for each of the bags of tricks, they're a No space limitation item. So you have to multiply entire cost by 2.

i thought it was a held space item similar to weapons. if notthat means that the total cost to make a weekly/monthly item is half as much for a specific slot item.

i thought the no space limitation was for things like ioun stones which are worn and active but not held (like a dancing lantern, or such. but not things like pipes of sounding or bag of tricks since you have to hold them to activate)

You know, I'm probably wrong. What you said makes a lot more sense then what I was thinking. I guess I should sleep before I try to do math.

Creating the item requires material components equal to casting the spell 50 times. If you figure based on the bag of tricks' costs that an item with weekly charges constitutes a cost multiplier of x/120 compared to a infinite-use item, then the material components for a 1/week item ends up being less than half the cost of simply casting the spell a single time. Buying a 1/week item for an expensive spell could end up being cheaper than buying a single-use consumable simply casting the spell yourself a single time.

For example, True Resurrection is a 9th level spell requiring a minimum of CL 17. 9 * 17 = 153.
Multiply the cost by 1,800 for a command word activation. 153 * 1,800 = 275,400
Add 50 times the material component cost to the top of it. 50 * 25,000 = 1,250,000 + 275,400 = 1,525,400
Make it a 1/week item, multiplying the final cost by 1/120. 1,525,400 * 1/120 = 12,711.66

And then if you also figure that a monthly charge is x/28 the cost of an infinite-use item based on the cost of the elephant, then your 1/month items are four times as expensive as your 1/week item. That's just counter-intuitive.

and thus why i asked for ideas on how to make then since the DMG does a piss poor job. it has items that have weekly/monthly but has no explination how. hell in one of the modules my DM used there was a orb that had a 1/week fireball use. i tried to figure out the price on it and couldn't.


these were my guesses ------------ what i actually calculated
daily is x/5
weekly should be x/35 --------------- x/120
monthly should be x/ 150------------- x/28

by my original esimation, i wonder what magical traps reset timers cost. eh doesn't work its CR based not specific cost it seems.
