Is that possible? I used the Infinity Explorer to check its stats, which revealed that it had a 100% resistance against crushing and slashing damage. However, its remaining resistances (e.g. fire) were all at zero percent. Still, attacking it with the Brimstone Hammer - a weapon which deals fire damage - seems to conflict no harm to it.
If anyone knows a strategy to dispose the spirit, if it now isn't invulnerable, then please share.
