Use Magic Device limitations

[Greenfield]

I get Deceive Device to let you take 10. I'm curious about +42 to the roll.

At 17th level you could have 20 points in it. Presume a Charisma of 30, counting stat items, I can see 30. There are Synergy bonuses available for specific things like Scrolls, but I didn't see any that apply to staves.

Where is the other +12 coming from? (Not challenging, just curious.)
<edit>
Never mind. Just caught your post above. a +15 ring? Wow.

Yeah, the ring isn't that tough to acquire. Market price of 22,500 gp means a base price of 11,250 gp and an XP cost of 900. My warlock's artificer cohort has all the cost-reducing feats from the Eberron campaign setting, so for him to create this ring would take 17 days, cost 8437.5 gp and consume 675 xp. Not bad considering the utility of the skill for a warlock (or an artificer). And that's also part of the motivation to find ways to "exploit" the UMD skill - to make sure I get my money's worth.

Where would I find a price progression scale listed for skill boost items?

I'm aware of a number of specific ones, but most are in the +5 range. +15 seems a bit much.

I'm also aware that not all items are created equal, despite the general rules for item creation. Their prices are supposed to be based on their over all usefulness, with the caster level/spell level formulas as a guideline.

Not sure if you knew this but the +15 to UMD is from an artificer infusion which is then cast in the ring and not from the ring itself.

Secondly, a Wizard's CL is all of his arcane casting levels combined, NOT a class feature.

Incorrect.

PHB pg 171

A spell’s power often depends on its caster level, which for most
spellcasting characters is equal to your class level in the class you’re
using to cast the spell.

A wizard 5 sorcerer 3 has a max CL of 5 for wizard and 3 for sorcerer not a max CL of 8 for either.

Some prestige classes add to the CL of a specific casting class.

No, the +15 is a permanent competence bonus on a ring, and the market price (22,500 gp) has been determined from the rules for estimating magic item prices, which can be found at Creating Magic Items :: d20srd.org

Additionally, if you check the basics of Epic Magic Items section of the SRD at Epic Magic Items :: d20srd.org you'll see that a skill-enhancing item isn't considered epic until the bonus to the skill exceeds +30. Based on the requirements for existing skill-enhancement items (Improved Ring of Climbing, for example) the creator must have ranks in the skill at least equal to the bonus they're creating. 15 ranks of any class skill can be reached by level 12, which conveniently is when you can take the Forge Ring feat.

As far as the artificer infusion of skill enhancement goes, that bonus is a circumstance bonus (Eberron Campaign Setting, page 115) which would stack with the competence bonus provided by the ring's enhancement. With my artificer at level 16, that would provide a further +10 bonus. Hmm, thanks for bringing that up!

A little OT but just a philosophical critique of your sig:

If nothing is true then this statement also cannot be true making such a statement absurd.

The statement everything is permitted is immoral, that means that to violate another person's individual rights is permitted.

The statement anything is possible is also not correct. The statement "wishing won't make it so" captures this idea.

Perhaps the problem is with your conceptualization of "nothing". You should check out Sep's story hour. From your statement I infer you're using a definition of nothing which is essentially "no thing". That's not the only meaning of the word...

The statement everything is permitted is immoral, that means that to violate another person's individual rights is permitted.

And it happens all the time, doesn't it? We couldn't begin to count the number of violations of individual rights that occur on a daily basis. And since many of these violations fail to result in any sort of accountability on the part of the perpetrator, it does seem that a lot of things that are immoral are indeed permitted. Sad, I think.

The statement anything is possible is also not correct. The statement "wishing won't make it so" captures this idea.

Now on this I'm going to have to disagree with you. I know my imagination is far too meager to ever encompass all of the possibilities of reality. And my experience is even more stunted. I have faith that reality can and will surprise me with the actualization of potential.

Darn, got meeting to get to...
