Here are some more screencaps of Inquisition’s skills, in this case for two Warrior specializations: Reaver and Templar. These are not all the skills but they still give us a pretty good idea of what to expect.
The Reaver specialization is all about increasing your damage output at the cost of losing health.
Templars are essentially the same defensive warriors as they were in previous games, but the skills are almost entirely new. A lot of cool support/buff abilities here.
