Knowstones

Topic: Things

Small stones, no bigger than a pebble, that when triggered (perhaps rolling between your fingers) can activate low level spells (no higher than 1st level, with most being common cantrips)

Oh boy, its time for the math!

The equation for generating relevant magic items is as follows:

((spell level) * (caster level) * (4000gp)) / (5 / (uses per day))

Therefore, a typical Knowstone would cost the following (assuming minimum caster level and 1 use per day):

• Level 0: 400gp
• Level 1: 800gp
• Level 2 (extremely rare): 4800gp

Or, if only at 1/week:

• Level 0: 60gp
• Level 1: 115gp
• Level 2: 690gp

What about some weird ones?

• Knowstone of Teleport 1/week (CL9): 5,150gp
• Knowstone of Wish 1/year (CL9): 335gp (what the actual fuck)
