I can help you here,I've played Spirit engine for 2 years and have beat the game 5 times with different combos.to beat him you MUST kill the familiar firdfst or it will drain you while the grandfather drains too,I suggest the rifleman attacking with
sharpshoot with the silver gun not the thunderstick one priest healing,and if you have a second priest healing to with a mana recharge amulet on the rifleman,if you have an energy person I suggest killing the familiar and then casting magic shield when the grandfather raises his impenetrable shield (about 1000 Health) make sure to heal and recover after this still heal with the priest(s) and block with the energy wizard(s) and attack still with sharpshoot...you might have to do it for a while if you die keep trying my best combo was mathiue,peter,andzepher.
