Rush of Blood is a weekly Slayer-themed combat Distraction and Diversion that can be played in Prifddinas, requiring at least level 85 Slayer and completion of Plague's End. It is run by Morvran Iorwerth, slayer master and former warband leader, and takes place in his dungeon underneath the Iorwerth Clan district. In the D&D, waves of different monsters, drawn from Morvran's assignment list, must be fought and one is given ten minutes to do so.
