The first image in this thread shows the guy as having 18hp and is diseased. Also, he's old. Without GoH, the Chalice or a source of regeneration, he will lose 1hp a month until he reaches zero (in 18 months time) and die. Technically, GoH and the Chalice won't stop that directly but there is a very strong chance that his disease will be cured before he reaches 0hp so he can continue to nuke armies with remote fire spells for months and years to come.
