My level 25 druid had over 1000 hp and around 700-800+ mana. I never looted a hero corpse, and I got all my gear from random kills. When you have 40 PKW since the last death, and you loot the best items from each kill.. you build up a nice set.
Its kinda neat to have that much health on a druid on low levels. Their abilities is rediculously powerfull since so many people level up in the wilderness around that level. With the protection skills that druids have, 1000 hps at level 25 makes you close to immortal :)
