I am in the middle of helping answer a question about helping a player create a Duskblade. I would be using @Ernir’s Psionic mechanics, Arcane flavor variant. I was wondering how different unconverted classes fit into this system, and specifically the Duskblade.
My initial reaction is to give them "very many" spell points. The Vancian base class gets a very, very large number of their frequently used lower level spells per day, leading me to believe the class was intended to have durability enough to keep pace with mundane characters in most situations. Also, the class relies largely on augment-scaling blasting spells, further increasing its dependence on a large spell point pool.
So far, I have based my spell point progressions on simple quadratic equations, tweaked as experience and feedback has started streaming in. My starting point would be to copy the Sorcerer progression. In the related question I suggested giving it more than the Sorcerer, but that included compensation for how thoroughly the Unearthed Arcana spell point variant shafts the Sorcerer with respect to spell points. Should that not be sufficient, I would start experimenting with increasing the multiplier of the quadratic coefficient (I would not like giving the Duskblade significantly more spell points at the lower levels) to something like 1.2 (from 1). This modified equation would give something like:
But again, my initial feeling is to copy the Sorcerer progression.
