The cosmic focus is one of the rewards from the Desperate Measures quest. It prevents Sprite Focus from dropping below 10% while excavating with the cosmic focus in backpack. The player must keep excavating for the effect to work; stopping excavating allows the Sprite Focus to drop below 10% even with the cosmic focus. If Sprite Focus is already below 10% while excavating, it will prevent it from dropping further.
It can be combined with a cosmic pyramid to create the cosmic accumulator (see guide).
If lost or destroyed, speak to Giles at Anachronia base camp to reclaim the cosmic focus.
