What about some Shields? Now with shield slots I feel like there is nothing that can be used in shield slot, so I came up with the following:
Force Field Shields:
It would work when you hold down the RMB and protect you from 200° practically leaving your back unguarded, and only effective to physical projectiles, and could act (toggle-able) as a Charging energy Crystal as It would take one to be crafted.
Same thing, but it would protect 360° and with a mode to auto activate itself, like a danger sensor (would be consuming energy to keep this sensor active) (a good item for the recipe would be iridium neutron reflectors), and could act as a Charging Lapotron crystal, since it would take one to be crafted, or an alternative recipe where you use your nano shield in to cut down the cost.
