5) Furious Attacks Ability. Don't know, if this is working as planned. When I use it with my bow and arrows, the arrows never get reduced, I don't even need to equip them. The bow's durability gets reduced correctly though. I also don't need to equip a melee weapon for the Blade dance ability.
6) Arrow Rain Ability: Outside the Fortress, but in "Arena" region. Using Arrow Rain ability resulted in a crash. BugSplat report already sent, with description: "arrow rain ability."
