Darkblood Banners are found in Maidenwood Castle and are similar to the Obelisks of the Isle of Eclipse . They can only be seen during Blackowl 's third quest in the area, which gives the player the task of destroying eight of them in return for a Hellrazor . If you hit a Banner two Darkblood Assassins will appear and attack you, even with their long bow. It is recommended to hit and run multiple banners to avoid being overwhelmed by the Darkblood Assassins. Running to a safezone, such as the middle of the castle, will prevent the pursuing assassins from attacking you, allowing you to destroy any previously hit banners with ease.
