Last night I was moving in to the later stages of the game and recently gained access to Psi armour and the Mind Shield.
If I recall, the description for the Mind Shield implies it is a defensive gadget, but I notice that (like the Psi armour) it provides a bonus to the Will of the wearer.
Does this bonus to Will mean it improves the 'attack' strength of a Psionic who happens to be using one? Or are Psionics' attacks uneffected by their Will score?
