Scion said:still, according to the base rules (which I believe do not let umd and usd to stack) I think that it would not be allowed.
Of course, I would still allow it![]()
Staffan said:Keith weighed in on the issue in the Keith Baker Q&A thread in General. Basically, he didn't think it'd be balanced to let the artificer do both magic and psionics, but a psi-only artificer would be OK - swap the feats for their psionic counterparts, and replace UMD with Use Psionic Device, Spellcraft with Psicraft, and Knowledge (Arcana) with Knowledge (Psionics). The Augmentation infusions would use psionic weapon/armor abilities rather than magic ones, and so on.
