Retooling Epic Item Costs

Pricing Metamagic Rods

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
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,

cost = (6p-3)x^2 -(3p-1.5)x +(3.5p-1.5)​

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
Prices are in thousands. There should probably be an epic multiplier applied for epic metamagic feats. So a greater rod of [+20 metamagic feat] would be 946K x 5 = 4,730,000 gp. Do you need more rows?

[edit] This post gives an explanation for how Tome and Blood priced metamagic rods. It might be that 3.5 metamagic rods are too cheap. Dunno.

How bizarre. I'd assumed that they were priced on the basis of a 3/day item, and was trying to work back from there to a 5/day (= unlimited uses) item for a base price. And ax^2 - bx + c just seems a very oddball way of doing it.

I'm thinking about cumulative effects - say you wanted a metamagic rod which both widened and enlarged a spell. Or rods which have a higher daily limit of uses. Or rods which double empower and maximize (= Intensify, old-style). It's hard to know when the epic multiplier should kick in.

Epic metamagic rods would be nice, but something which scaled more flexibly would sit better with me. Assuming that all epic metamagic rods are effective on spells of 1st-9th level, how would you feel about this formula:

(Total metamagic level adjustment)^2 x (daily uses) x 4,000

This agrees pretty closely with a greater quickening rod (192K vs 170K) and your hypothetical +20 metamagic feat rod (4.8M vs 4.73M) but would allow more customizable rods. E.g. a 5/day Intensification Rod would cost 7^2 x 5 x 4000 = 980K etc.

I'm thinking that Jake ought to be pondering a backup plan for when he runs out of epic spells.

It is a very peculiar formula, and I haven't been able to discover a rationale for it.

If p is the total metamagic level adjustment, the T&B formula comes out to (2p-1) x (daily uses) x 16,200. The linear factor is awfully suspicious, though. I'd go with your formula.

How about an item that conveyed an extra AMC? Or an epic spellcasting slot (as if by the Epic Spellcasting feat)? If we are exploring feats that duplicate items and items that duplicate feats we should address this possibility. They scream brokenness to me, but perhaps I am too slow-witted tonight to see around the difficulties they present.

Caster Level: 21st; Prerequisites: Craft Rod, Craft Epic Rod; Market Price: ?

Should this item even exist? How would you cost it? Should it be a minor artifact?

I'd rather it didn't exist. I'm hoping that our system is tight and powerful enough that we don't need such items. It also defeats one of the main purposes of having a spellcraft prerequisite system; to make it impossible to buff.

The only reason I might list such an item is because people will expect to see something like it. I would rather it be priced pretty severely, so that folks will normally choose something else. Perhaps 5 times as much as a weapon bonus. I.e.

1,000,000 + bonus cubed times 2000


More than that and people will house rule it down. Less than that and it would be a significant item; perhaps a must have item. A +10 item for 3 million might in fact be a must-have item for a 50th level character. It is the equivalent of a 100,000 gp power component for every spell (400,000 if not a preferred mitigation) and could pay for itself within days.

A +5 item would be 1,250,000 for a 37th level character. I think that would be OK.
Since we are now using half the ELH values for items (base value x5), my proposal would translate into bonus^2 x 50,000. Or, if it is an artifact, bonus^2 x 100,000.

This is priced rather conservatively- a cheaper price might be appropriate. Perhaps much cheaper. I find Temenun very interesting. How best to translate him in our current Epic Magic system? The Token of Cheshne, among other things, gives a +50 bonus to Spellcraft. Now our system generally gives involves smaller numbers than the ELH system, so I'd hazard a guess that this would translate to +30 ranks. Temenun has 38 ranks of Spellcraft, so we'd be looking at SP 68 spells.

Hmmm. His epic spells don't fit the pattern we were considering for sorcerers; they are too varied. If we pretend that he is casting epic spells as a wizard, we'll have to give him two more Epic Spellcasting feats. I wonder if we can replace the Spell Focus feats with Epic Spellcasting. They are default Ak'Chazar Rakshasa feats, but maybe he took Divine Ak'Chazar Metamagic feats instead.

Whatever we do with Temenun's feats, I think a fruitful approach would be to take some ELH spells, decide what SP they ought to be, and reverse engineer the seeds so that they fit.

For instance, Temenun has 3 ranks more than he needs to cast reflect assault, so perhaps we could see whether we can design a [reflect] seed that produces that effect at around SP 65 or so.

I mention reflect assault because I think it was particularly cool:

4) Reflect assault: reflect (+27), 20 attacks (+60), +1000% duration (+20). Reflect first 20 ranged or melee attacks on attacker. DC = 107.
I'm gonna have to check the [summon] seed to see how this one comes out:

6) Chthonic summons: summon (+14), 1-action (+20), increase CR by +30 (+60 DC), +1000% duration (+20), 400 XP (-4). Summons a chthonic balor for 11 mins. DC = 110.
I don't remember anymore, but when casting an ELH spell, can you take 10 on your skill check? If so, then it shouldn't be that hard for a wizard to devise a spell that gives a modest penalty to Spellcraft checks in an area- this would gravely hinder most epic spellcasters, who, when they take 10, generally succeed by only a point or two.

Hmmm. I think I'll continue the discussion of the spells in the appropriate thread. If we get the Token figured out (preferably here), and Temenun's spells, we could probably add him to the Epic Characters thread. With a link to the ELH version, of course.
