The Noctuary (D&D 3.5e, Level 20+ Adventure)

[Feathersnow]

Treat the base incarnum dragon as having meldshaper levels equal to twice its age category, and advance from there. I think this is a coherent extrapolation, let me know if something breaks.

Here's the thing- it becomes ambiguous because the amount of soulmelds available is determined by half age category rounded up, not meldshaper level. I suppose I could assume that that's one soulmeld per four prestige class bumps, which is in keeping with a soulborn, which is the class that is called out as the source of available soulmelds.

Edit- my build is a juvenile LE incarnum dragon that prestiges directly into Witchborn Binder. I am working on her in case One Ear is too "goody-goody" for an LE party.
