Firestorm is a level 1 skill from the Druid's Elemental Skill Tree.
Required Level: 1
Synergies: Firestorm is boosted by:
Details: Wielding this ability, the Druid projects waves of molten earth that spread outward and burn a wide swath of destruction through his foes.
This is the same ground fire attack that Diablo uses (and you see the graphic as part of Mephisto's death animation as well) and it's fun to use for the Druid, but doesn't do nearly enough damage to be effective long term. This skill is tremendously damaging when Diablo casts it on Hell, since he gets many more fire streams then he has on Normal. If you are in close, you'll get hit by dozens of the streams, all of them doing moderate damage, and adding up to be enormous damage all at once. The Druid doesn't get additional streams like that, so even at very high levels this is no better than a very weak, short duration, moving Fire Wall.
