[QUOTE="Cheiromancer, post: 3231111, member: 141"] [b]Pricing Metamagic Rods[/b] The following are the equations for the cost of the rods whose metamagic feats are +1, +2, +3 or +4, respectively. x = 1 means a lesser rod, x = 2 means a normal rod, and x = 3 means a greater rod. [code] 1s 3x^2 - 1.5x + 2 2s 9x^2 - 4.5 x + 5.5 3s 15x^2 - 7.5 x + 9 4s 21x^2 -10.5 x + 12.5 [/code] There is a clear pattern; the coefficient of x^2 increases by +6, the coefficient of x decreases by -3, and the constant increases by +3.5. Or, if p is the LA of the rod (its "plus") then, with the values for x defined above, [indent]cost = (6p-3)x^2 -(3p-1.5)x +(3.5p-1.5)[/indent] Which yields the following table: [code]plus lesser normal greater 1 3.5 11 24.5 2 10 32.5 73 3 16.5 54 121.5 4 23 75.5 170 5 29.5 97 218.5 6 36 118.5 267 7 42.5 140 315.5 8 49 161.5 364 9 55.5 183 412.5 10 62 204.5 461 11 68.5 226 509.5 12 75 247.5 558 13 81.5 269 606.5 14 88 290.5 655 15 94.5 312 703.5 16 101 333.5 752 17 107.5 355 800.5 18 114 376.5 849 19 120.5 398 897.5 20 127 419.5 946[/code] Prices are in thousands. There should probably be an epic multiplier applied for epic metamagic feats. So a [i]greater rod of [+20 metamagic feat][/i] would be 946K x 5 = 4,730,000 gp. Do you need more rows? [edit] This [url=http://www.enworld.org/showpost.php?p=1964031&postcount=10]post[/url] gives an explanation for how Tome and Blood priced metamagic rods. It might be that 3.5 metamagic rods are too cheap. Dunno. [/QUOTE]
