This terrible force of nature's vengeance rains down flaming stones around the Druid who cast it, pummeling any opponents foolish enough to be caught in its fury.
Armageddon works a little differently than expected, similar to the Sorceress' Thunder Storm. Once cast it follows you around. This makes it highly imprecise to use, and compared to other spells in Diablo II it also lacks raw damage potential. These two things combined makes Armageddon far less powerful in the hands of the Druid compared to what a Sorceress can perform. However, Armageddon can be useful.
The Druid can use this skill while in Werebear or Werewolf form, which certainly adds to its use. However, the number of synergies a druid must invest in to make his elemental skills powerful often makes this skill suffer while the druid spends points into other Shapeshifting skills.
