Khagra the Usurper
This warband leader has a decent stat card. Her big thing is that when she takes a fighter out of action, she can desecrate an objective. We will have to see how this interacts with the objective-based warbands out there.
Zarshia Bittersoul
Zarshia is the the wizard win to her sister Khagra's warrior yang. They even share the same desecrate ability. Be careful what you wish for though, as her magic attack can cause backlash damage.
Dour Cragan
This guy is slow, but has a massive attack. It also gets cleave when inspired. He also has two abilities that can desecrate objectives.
Razek Godblessed
Razek has the same two great ways to desecrate an objective that Cragan has. His big thing is that we gets an additional attack and defense die when inspired.
Khagra's Ravagers are designed specifically with the aggro play style in mind. They are a great counter to objective based opponenets.
The Cards
The warband's new cards introduce some new interesting ways to claim victory in Direchasm. Brutal Desecration allows you to earn glory as soon as you use the new desecrate ability on an objective.
Eye of the Gods is a pretty unique card. You can upgrade Khagra after you down the enemy leader. You choose the effect instead of it being random, giving you more control.
There are also some good upgrade cards that help smooth out the warband's weaknesses like lack of range. Sword not long enough, kill it with fire!
Now here's the full list of cards that come with the Khagra's Ravagers expansion.
