I am having an intelligent magic item built, and want to make sure that the costs are appropriate. Here is what I have so far:
Magic Ring or Amulet (+500gp for being an intelligent item)
10 Int, 10 Wis, 10 Cha
Telepathy (1,000gp)
Senses (120 feet) (1,000gp)
Darkvision (500gp)
1st level spell 3/day (1,200gp)
2nd level spell 1/day (2,400gp)
3rd level spell 1/day (6,000gp)
4th level spell 1/day (11,200gp)
+1 AC (insight) (2,500gp)
+1 saving throws (competence) (2,000gp)
Please let me know if this is priced correctly or not. Do I add 50% to the total cost for multiple different abilities? If I am missing anything, please let me know. Appreciate the input.
So, it's a ring of +1 insight bonus to AC and +1 competence bonus to saves as the base item? That would cost you 2500+(2000*1.5)=5500.
Now to add the intelligent abilities:
500 for being intelligent with base stats (Ego +0)
1000 for telepathy (Ego +1)
1000 for 120' senses (Ego +0)
500 for Darkvision (Ego +0)
1200 for 1st level spell 3/day (Ego +1)
2400 for 2nd level spell 1/day (Ego +1)
6000 for 3rd level spell 1/day (Ego +1)
11200 for 4th level spell 1/day (Ego +2)
Total: 23800, Ego 6
From the base item you add the 5500 (Ego +2) and get 29300, Ego 8.
Note: This is just an estimate. Magic item pricing is entirely based on guidelines, not rules, and are designed for a GM to create new items that the players can then make, not for the players to custom-build items to their exact requirements. As a GM, I'd probably price something like this closer to 50000, depending on the spells and what caster level they're at.
Also, keep in mind that the item is using the spells when it feels like it, not necessarily when you want it to.
