These are items that will have beneficial effects lasting for the duration of that cycle. They can have passive effects (for example the Reactive Stabilizers, which reduce the chance of being knocked down by enemy attacks), or activate under certain conditions (like the Fractal Nail, which increases your damage whenever you have a suit malfunction). Some rare artifacts like the Astronaut Figurine can even resurrect you on the spot, which can make the critical difference between triumphing against a Boss battle or respawning back at Helios in defeat.
