If you die, the boss becomes immune to all damage, and your run stops. The boss spawns after 10s, so use those 10s to load and buff. Your DPS-per-skill/effect is shown inside the raid. Each tree competes vs other players of the same tree (scout vs scout, wizard vs wizard. You may rank with different trees: warrior, archer, wizard, cleric, scout. Max 7 runs for ranking mode (for your team). Eat squire's food, go use enchanter's shop, get weapon buff, squire ARTS buff, buy the special boss-raid-potion at gemfeud shop, and get priest &pardoner buffs (both shop and manual buffs) before you enter.
Level required: 440+ to enter (press F10 dungeon interface and go to 'weekly boss raid'). Crit chance % = (your critical rate / enemy's critical resistance)^0.6 -1
