Now I'm surprised. The druid has the coolest area spells in the game (Fireball is just nothing compared to those), not just powerful, but the animation looks pretty cool, too! She's become the caster I mainly rely on beside the Sorceress (which is also a big surprise, I've always played a Wizard - but that's another matter...)
And I found the Holy Hammer of Lucerene for her in the Monastery, which does 10d+3 damage AND works as the Club of Disruption: all undead must make a Fortitude save or die
So, it seems that the Druid is not as useless as it seems until lvl 5
