Rune
Once A Fool
Are you talking about the shields?In the fight scenes, they have some sort of armor that I would steal for D&D, but not sure the stats of it. I could just be mage armor for the +3 AC. It also looks a bit like some sort of psychic energy, but I would stay away from psionics in my games. It could be more of a force property added to light armor with the standard +1 to +3 and maybe give it a bit of something like protection from magic missiles.
If they’re accurate to the book (and if my memory serves), they repel faster forces (particularly ballistics), thus the need for a melee fighting style with intentionally slowed-down strikes. The downside being that a lasers hitting them will trigger a nuclear reaction.
