General Cost in XPNote if you use the Kaorti discount you need to add 13% of the gp value when it was applied to the xp needed to craft and that xp can not be reduced in anyway without reducing the amount of gp you are saving.

Regenerating XPThere are a variety of ways to reduce xp but there is a non-super cheesy way to get a continuously regenerating xp supply. Ambrosia is a substance that can be used to replace 2 xp for crafting purposes per dose. Distilled Joy is the spell that creates Ambrosia by using a person in continuous pleasure. The major downside to Distilled Joy is it has a casting time of 24 hours. The way to get around that is by using a
Spell Clock that casts it once every 24 hours, a magic trap with the spell cast into it as a Spell Like Ability, such as by a Factotum, or using a Limited Wish. One way to keep the person in a state of continuous pleasure is by putting the nipple ring from BoVD that turns pain to pleasure on them then putting them near a symbol of pain. For maximum effect place the subject in overlapping Manifest Zones, one providing the timeless trait and the other providing the fastest flowing time trait you can find (in Eberron's case Dal Quor). These manifest zone are created through the psionic power Anchor Plane. To get a pool of people willing to act as xp batteries you simply need to use the feats Leadership, Extra Followers, and Assemble the Horde.
Limited Wish casting of Distilled Joy or Spell Clock (160k) to make Ambrosia - BoED
Nipple Clamp of Exquisite Pain (8k) - BoVD
Symbol of Pain (Wiz5, 1k) - SRD
Manifest Zone - ECS
Anchor Plane - FoE
Once completed, this makes the above section for lowering XP costs obsoleteAlternatively the "LE medicant scheme" works as well. Please note that my corrections are in italic (except for the added periods).
Step 1) Set up free hospitals.
Step 2) Extract liquid pain from people suffering diseases (they're acceptable targets). Magic trap or spell turret or spell clock or something.
Step 3) Use some sort of magic trap of cure disease or something.
Step 4) Undercut all the good churches.
Step 5) Drive all other medical services out of business. You are now necessary to society.
Another method that can be used is the Thought Bottle. It allows you to basically 'save' how much xp you have (minus the 500 xp cost for using the Thought Bottle like this) and then 'reload' to that amount at a later date. If done multiple times that 500 xp can add up so the number of times this is used to 'save' your xp should be minimized. One way to minimize the xp lost is to use two different thought bottles so you only lose 500 xp even after using the first thought bottle many times.
Another one:
[/spoiler]
Step 2: Burn all of your available XP making stuff.
Step 3: Get a restoration cast on you, removing the negative level and resetting your XP to the minimum for your original level.
Repeat as necessary. This does cost you 100gp per casting, but that's a pittance compared to what you'll be saving by making all of your own gear.
Alternatively to these options, automatically-resetting Magical Traps or Spell Turrets can enable several joy inducing spells, like Good Hope or Elation to be cast repeatedly, thereby enabling the other Ambrosia traps to continuously produce their extract. Further, people would
want to go into these devices, especially if you stack several pleasure-inducing spells into them.
Finally, if an Artificer wishes to have arbitrarily large amounts of magic items for purposes of draining for Craft Reserve, than all they need to do is combine the spells Wall of Iron, Transmute Metal to Wood, Wood Shape, and Ironwood, so they can make unlimited +1 Breastplates to drain for Retain Essence. He could also simply use this combination, perhaps in a Wondrous Device or some Magic Boon traps to simply equip a city.
