Mana Globe

Mana globes and a level up.

Mana Globes are orbs of magical energy that function much like health globes; they restore mana (25% of the maximum was the listed amount) when a character runs through them. As you might expect, they look just like health globes, but are blue, instead of red.

No mana globes were seen during the BlizzCon 2008 demo play, and they are only mentioned in the description of the Mana Recovery spell. It's not known if they ever drop other than when a Wizard is around, with points in that skill, but it seems likely that they only drop when a Wizard is around, and considering the loot system, also only visible for the Wizard. If they do drop for all players, it's assumed that other characters would share in the benefit, as they do with health globes, but this is just conjecture.
