mithral breastplate +1 of light fortification with +1 defending parrying silver armor spikes
permanently ironwooded darkwood (treat as mithral but not as durable) breastplate +1 with +1 defending parrying ironwood armor spikes (for the Druids; not getting light fortification because saving up for 'wild')
+1 permanently ironwooded darkwood barding (for level 5 druid forms that aren't humanoid and thus can't wear human armor, like a Baboon can. Things like Crocodile, Deinonychus, or Leopard)

+1 Keen Adamantine Falchion
+1 Heartening Bashing Darkwood Heavy Shield with +1 Psychokinetic Adamantine Shield Spikes (This would be used two handed as a primary weapon, so as to get two handed weapon bonuses with shield bonuses. fighting two handed with a single spiked shield is a realistic, historic combat style, btw.)

Perhaps the best item in the entire DMG+SRD is the Psychoactive Skin of the Proteus.
