Curious but is there a build that does a lot of damage and burns mana? I'm thinking back to my diablo 2 days when I would stock up on mana potions and spam high damaging attacks. So far I've tried a spirit nature summoner build but I'm curious whether there is a high man burn high impact skill I can spam?

Feel free to give me your input on your builds and preferences.

Not sure, but Flame Surge and Ice Shard would both use a lot of energy since they're channeled skills. They certainly did back in TQIT, not sure if that's been changed in the AE version.

Trying earth. Seems you can easily deplete mana quickly with this profession. Early stages, level 3 and already running out of mana often.

Think Ternion Attack in Spirit also uses a lot of energy. That's why people often use just straight weapon damage on one weapon slot for trash mobs and keep Ternion on the second to deal with bosses.
