I believe Mage: the Ascension has artifacts that can be used as weapons. Each level of health destroyed by these knives is converted into a point of Quintessence.
If a group of mages were to use some kind of awakened magic - possibly a ritual - to enact a similar attack, the attack might benefit from the use of some level of Correspondence. Correspondence would allow a ritual group to target some potential victim far away.
The spheres of Life and Prime would be necessary to destroy at least one level of the target's life and to convert it into Tass or Quintessence. Depending on interpretations of rules, the life-force might form into lumps of Tass that would stay in the victim's body, or perhaps the Quintessence could be leeched back to the casters.
Many years ago, in 1st edition Mage: the Ascension, I knew a Storyteller who ruled that this type of spell was easy. That storyteller claimed that this type of work would just require Life 3 Prime 3, and that each success would cause a level of the victim's health to be transferred to the caster's Quintessence pool.
However, as time went on, various critics decried the original spell as overpowered. Some critics claimed that the spell should require Entropy. Other critics claimed that Prime could not tear the Quintessence out of any living pattern and return it in a usable form. Some of these criticisms may have been based on printed rules that were released long after 1993.
Explicit question: Does 1st edition Mage: the Ascension allow Prime 3 and Life 3 to convert a target's life into Quintessence?
Side note: Even if this type of spell is legal according to rules-as-written, many World-of-Darkness fans would probably hate it because it allows mages to upstage vampires. If a mage can use a life-draining attack, like a vampire, the players who invested time in vampire characters are likely to object.
