As a reaction, which you take when you are reduced to 0 health, you can choose to let your soul emerge from your body to fight on. Your body remains unconscious and subject to death saving throws as normal. At the beginning of your next turn, you manifest a spirit form in your space that picks up your weapons and continues fighting on, acting on your turn and every one of your subsequent turns under your control. Your spirit form has your physical attributes and Defense, as well as your weapons and ammunition, and can move through other creatures and objects as if they were difficult terrain. This form is immune to cold, necrotic, and non-magical weapon damage. Your spirit form has access to all of your abilities.
If your spirit form takes any damage or you are no longer unconscious, your spirit form vanishes. If your spirit form vanishes, it drops your weapons in its space.
You can expend 1 additional mana or psi to stabilize your dying body.
