Psionic Army Design?

[ExLibrisMortis]

Gotcha on the disciplines, thanks.

For the Constructors -
Feats:Spell Focus/Augment Summoning/Imbued Summoning/Dual Plane Summons
- Use Venomfire buff with Imbued on AC
- Get an extra improved AC with Dual Plane

No. Constructors build armies of astral constructs. Dual-Plane Summons experts can do the Imbued venomfire trick, but they don't build astral constructs. They summon creatures from the summon monster lists, with the AC abilities on top.
