"Spiritists, another of the base adventure schools, tap into the life force of a monster and drains it?earning them the reputation of a sinister mage. They also use abilities and spells that allow them to share this life force with teammates, making them very useful to have in a group."

Granted I only have 50 lvls into spiritist so far, but I haven't noticed and ability or spell other than self sacrifum that allows me to transfer life to those in my group. Hopefully the spirit epic spell will be like ethereal parox, only will HoT for the entire group.
