Torchlight II's Charge Mechanic Explained, Trailer

Runic's official Torchlight II website is sporting the first details on a new "charge" mechanic that they're adding to the game, which allows a character to build up a class-specific energy that can be unleashed during tough battles. And to give us a better understanding of the mechanic, they've released a trailer showcasing the Berserker Frenzy in action:



And a snip from the text covering each class separately:
The Engineer

The Engineer's weapons and armor can only channel so much Ember before the pressure reaches a critical level. When charged, the Engineer can vent some or all of this excess Ember energy in the form of potent attacks!

The Berserker

A Berserker's fury builds until flesh and bone can no longer contain it! Once fully charged, the Berserker's rage converts all successful attacks into devastating critical hits, and few opponents can stand in their way.

The Outlander

An Outlander's fighting style builds in speed and precision until it reaches a fever pitch. While charged, the Outlander becomes a whirling dynamo, moving faster and faster and striking where it hurts the most!

The Embermage

The Embermage's power stems from control, and control requires concentration. When fully charged, the Embermage enters a trance-like state of total focus, effortlessly unleashing powerful torrents of pure magic!
