what exactly does the yellow orb do
Don't equip it--it Craig didn't fix a fork bomb associated with it and the game crashes if you keep it on too long.
See the orb walkthrough for an explanation- it does exctaly the same as the yellow orb in TRPG2.

It boosts you Psy regen. It's useful if you prefer high costing abilities.
