Sucellus' Hammer

Origin
Sucellus is depicted as a powerful god always carrying a large mallet and sacramental bowl. He was originally a Celtic deity but evolved to become worshipped in the Gaulish pantheon. Some surviving images show him carrying a large wine barrel, alongside the nature goddess Nantosuelta or followed by a loyal dog. Although his true representations remain uncertain, one version stipulates his mallet can revive the dead earth, but can also give those on the receiving end a quick demise.

Effects
Causes whatever it touches to be renewed to full vitality and strength, especially if the subject is the equivalent of dead or expiring at the time. This includes plants, animals, people, structures, cities and even words. However, a second hit will cause the subject to permanently die, with no possibility of return.
