An Intelligent items can be made which is capable of casting Glyph of Warding 1/day for a mere 6000 gp plus the cost of a masterwork item. 3/day costs only 18000 gp. No at-will option exists for the third level spell short of a Limited Wish at-will 7th level item for 182000 gp (which is very much overkill), but Greater Glyph of Warding can be acquired at will for 132000 gp. The WBL guidelines indicate that you can afford the 1/day version at level 4 with 100% of your wealth (good thing you get those clothes for free!), the 3/day version for 77% of your wealth at level 7, Greater Glyph of Warding at-will for 94% of your wealth at level 13, and Limited Wish at-will for 99% of your wealth at level 14. If your DM uses the common 'no one item can be more than half your wealth' houserule, you need to wait 2 additional levels for the regular Glyph of Warding and 3 for the Greater Glyph of Warding or Limited Wish.
When components are consumed, exactly, is super unclear. Regardless, it is clear that whatever order is chosen, that order must be consistent. This is important.
You still have to cast (like, the whole thing) a spell in the same round to get the Blood Money to activate. Fortunately diamond dust is a super common material component. There are two good ways to get extra material components for this from Blood Money: the first is by casting a spell with an optional diamond dust material component, and the second is by having two Blood Money effects active when casting any spell with a diamond dust component. Either of these methods is sufficient for our purposes, though the latter can be achieved as early as level 6 (by an Occultist 5/Wizard 1) while the former requires that one wait until level 17 for access to Miracle (As far as I can tell), assuming in both cases that early-spell-access methods are not used. In any case, it is possible to produce the diamond dust this way, but it only lasts for a round.
Components created by an ally with Blood Money can be used by you, if they are extra components as described above.
Thus one can make this work as follows:
- Our party consists of one Occultist 5/Wizard 1, one Cleric 6, and one Wizard 6.
- The Occultist uses Talismanic Implement to store Blood Money contingent on the casting of Blood Money with the implements.
- The Wizard casts Blood Money while using the enchanted implements, triggering a second Blood Money.
- The Wizard casts Recharge, producing 500 gp of spare diamond dust for our Cleric.
- The Occultist uses his readied move action or appropriately timed initiative count to transfer the dust from the Wizard to the Cleric
- The Cleric's casting of Glyph of Warding consumes 200 gp of dust.
- The Cleric heals the Wizard of the STR damage via any of myriad methods.
N.B. When the Cleric begins casting is not specified. If components are needed at the end of the spell, as the answer linked in the beginning indicates is preferable, the production of components should be timed so that the round on which they are needed is the round on which they are provided, so in this case the casting should begin before the components are on hand. If they are consumed in the beginning of the casting, as is indicated in the second quote in the answer, the casting should begin when the components are provided. If it's somewhere in the middle, adjust accordingly.
In fact, even if your GM rules that you have to have the components to start casting the spell, and you have to have them the whole time, and they are consumed at the end of the spell, this still works, because you can use your own, 'real', diamond dust up until the round the dust is consumed and then swap in the Blood Money components in the last round, effectively turning a 200 gp material component into a 200 gp focus.
This can be accomplished easier via other methods of contingency and/or with less people at higher levels, when diamond dust consuming spells become available to the Occultist (level 7 gives Stoneskin) and when free contingency effects (e.g. via the eponymous Contingency) become available to the Wizard. Technically Contingent Scroll makes this feasible at level 7 as well, but that effectively costs 25 gp to use so it's not quite free (though it is heavily discounted).
Obviously, this works equally well for Greater Glyph of Warding by the time you can cast it.
