I was surfing the internet and this partly amusing but potentially useful description of dwarven holy sprits appeared. The description of dwarven holy spirits looks most compatible with 5ed. That said, converting a Constitution save to a Fortitude save should make the stats compatible with 3.x edition or 4th edition.
I would say the most renowned dwarven spirit to date and in ancient times, is that rare, yet plentiful Gutbuster brew.
The Gutbuster Brigade of warriors out of Mithral Hall is one such example of a Faerun-wide troop of hand to hand, exotically armored battle-dwarves that send fear into any army intelligent enough to know what they are.
