Upon an ally dropping to 0 hit points within 60 feet, you can freeze them in time. They retain their exact position and pose as well and cannot be damaged further by non-magical means. The ally cannot make death saving throws during this time. If the spell is dismissed by the caster, the ally becomes stable. The caster can opt to sacrifice some of their life in order to heal the ally. The caster takes 1d4 force damage and the ally is healed for that amount plus the total number of spell slots you have remaining. If the caster loses concentration due to damage, the spell ends the caster takes half of damage and the ally receives a death fail. Due to the mal effects of time manipulation, this spell can only be used safely once per ally per long rest or risk taking 1d12 force damage for each further attempt.
