Psiconics in the Eberron Players Guide? Perhaps? Like post the Kalashtar race and a Psionic class they can play with? Naw. I'm reading too much into it.
I would really like to see an analysis of applying Conditions on the fly to actions the rules don't cover, like Page 42's famous way of applying damage the same way.
I would like a collection of 'grab-bag' monster powers/templates ala 3e savage species. Easy ways to tack a third arm on an orc or something. I know I can do it myself, but I am always cautious of balance and proper xp.
Also would like some player templates so one of my long time players can bring in his half-celestial / half-dragon into the system.
Don't misunderstand me when I ask this, but how the hell does someone accidentally mispost is a thread that hasn't even been on the front page in months?
Well, since it's here...
PHB4 Shadow, Primal and Martial Heroes
The Bright Plane: Secrets of the Feywild
From Beyond: Secrets of the Aberrant
Draconomicon 3: Gem Dragons
Since this thread has been raised from the dead inadvertently...
PHB4: Shadow, Martial, and Psionic Heroes (presuming PHB3 has only one psionic class per role) - Includes Beguiler/Illusionist, Necromancer, a Dex-primary/Int or Cha secondary martial class along the lines of the 3.5 Swashbuckler, and Soulknife as a Psionic Striker
A campaign setting that introduces Birthright-style rules for rulers (or perhaps a section in DMG3)
