There are base gold costs for constant skill-granting items (http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm), but I cannot find anywhere what the caster level requirements should be for such items. There are no high-level +skill items without other craziness that I can find, so it is difficult to judge what the progression should be. Is there a guideline anywhere for this issue?

e.g. slippers of tumbling +5/+10/+15/+20/+25/+30 competence bonus to tumbling


Skill items don't have caster level requirements. Just like most magic items don't have caster level requirements, other that "whatever it takes to cast the spells involved". (cite)

The DMG guidelines for custom items don't say how to choose crafting requirements at all, let alone specifically for skill items.

Most existing skill items' crafting requirements fall into one of two categories, with no apparent rule to predict which. They even often come in both versions for the same skill:

  • A 1st or 2nd-level spell which is thematically appropriate to the skill, and which doesn't scale depending on the magnitude of skill bonus.
  • Or, no spell but the crafter must have skill ranks equal to the item's bonus.

Therefore, you should be able to craft a +30 Slippers of Tumbling at character level 3, if you somehow had enough money for it. But if your DM is being stingy, you might need character level 27 so that you can have 30 skill ranks in tumble. The crafting requirement definitely won't be anywhere between those two.

Existing skill items, sorted by type of crafting requirement, from DMG and MIC (I haven't looked through other books for examples):

Ring of Chameleon Power, +10 hide (DMG): invisibility (Sor/Wiz2)
Robe of Blending, +10 hide (DMG): disguise self (Sor/Wiz1)
Circlet of Persuasion, +3 to all Cha-based skills (DMG): eagle's splendor (Sor/Wiz2)
Eyes of the Eagle, +5 spot (DMG): clairvoyance (Sor/Wiz3)

As topquark mentioned, there is no caster level requirement for skills in either the DMG or MiC, additionally a look through EL(Epic Level Handbook) shows no requirements or limits either. The epic level handbook only gives one example of skill bonus, but its pricing follows that given by the DMG, even if it has a CL of 20th.

What does limit PCs acquisition of high level skill granting magic items is the exponential growth of costs. A single magic item with skill bonus costs: $$ Bonus^2*100gp $$ That combined with the DMG recommended maximum value per item:

...you can limit him to owning no single item worth more than one-quarter of that[maximum wealth]... (PG199 DMG3.5)

Breakdown of bonus and minimum level achievable vs DMG recommended Level

Bonus     Cost         MinLeVeL(Wealth%)   Recommended(<25%) 
+5        2,500gp      3rd(93%)            6th
+10       10,000gp     6th(77%)            10th
+15       22,500gp     8th(83%)            12th/13th
+20       40,000gp     10th(82%)           15th
+30       90,000gp     13th(82%)           18th
+40       160,000gp    15th(80%)           20th

The relative power excessive skill bonus grant is much lower as compared to other items. I.e. a +30 ring is 90k, a ring of three wishes is 97k.

Final note, since skill bonuses are competence, no stacking. Alternate possible bonuses that would stack(like luck) are about 10-20 times more expensive.

  • \$\begingroup\$ Good call on the price comparison. There comes a point quite early on (unless you're a truenamer) of diminishing returns for a lone, custom magic item that grants a named skill bonus. (Although, as a nonstandard wish, I shudder to think of the glee an evil DM would feel—and the pain and suffering he'd inflict—upon a PC making the wish I wish to be the best best acrobat on the Material Plane!) I look forward to your formatting. \$\endgroup\$ – Hey I Can Chan Apr 23 '17 at 11:40
  • \$\begingroup\$ The epic items guide mentions enhancement bonuses to skills being capped at +30 for items, so I opened another question about that as well, because that would imply both competence and enhancement bonuses to skills from items \$\endgroup\$ – Wannabe Warlock Apr 23 '17 at 18:38
  • \$\begingroup\$ I was pretty sure that non-epic items for skills was capped at +15... but I haven't found the reference, yet. \$\endgroup\$ – nijineko Apr 23 '17 at 19:51
  • \$\begingroup\$ @WannabeWarlock checked that link, not sure where the reference comes from, since it isn't in the MiC DMG or EL that I can find. Maybe it was errata'd at some point. \$\endgroup\$ – spade Apr 25 '17 at 14:21
