I am playing a fairly high optimization campaign where I play a Wizard/Shadowcraft Mage/Shadowcrafter/Shadow Adept. Like I said, a fair amount of optimization is necessary, but 'broken' is frowned upon (i.e. Shadow miracles, and that kind of stuff). The rest of the party is rather large and includes a RKV (BSF), an Erudite+Arch Psion (blaster), a druid (with dragon wildshape+planar shepherd, but I've never seen him use any of it), a rogue build that I'm not super clear on the details (glass cannon), a lyric thuermaturge/sublime chord (face+dispeller) and a wizard/abjurant champion/paragnostic apostle/saint (gish). Many 'tricks' are acceptable for example: I am currently running with earth spell+residual metamagic+0th level silent images+etc., but force caging/trapping the soul everything is not okay.
Despite the fact that we are level 17-18, we fight mostly epic monsters. The DM is generally one person, but could be variable, and we generally don't play with everyone present.
*Eventually*, we will be entering epic levels, and I am at a loss as to go from there. I am not super familiar with epic levels or epic spell casting. However, most of my party has run epic characters. From what I am aware of, they have mostly maintained the epic spell casting rules, but done away with the epic spells provided. In effect, you still take a feat for epic spell casting and epic spell casting slots, but need group approval for epic spells specific to your character. Shadow conjuration/evocation has not been discussed yet, as it has never come up before.
While epic level is on the horizon, it is certainly inevitable. I am mostly making this post as a thought experiment. I do not see many epic level postings on this board. I am wondering what are decent options for how to proceed as an epic Shadowcraft mage? How should epic shadow conjuration/evocation function?
I have been considering suggesting implementing this:
http://www.giantitp.com/forums/showthread.php?t=37410 instead of epic spellcasting. I think it is a better system, but I know a lot of the other players (along with the DM) are a fan of making epic spells, even if they agree the epic spellcasting system has its flaws.
Buildwise, I have been considering the following:
-Ultimate magus (with a beguiler entry)
-Anima Mage (with a binder entry)
-Continuing Shadowcrafter progression
-Mind Mage (from Dragon Magazine [would require approval] with a psion entry)
Keep in mind, I'm tending towards a practical optimization standpoint, while trying to maintain fun/relevance for my party members and not frustrate the DM. I tend to focus on summoning+battlefield control.
