A second quest kicks in — these three steps get you from "quest complete" to "actively clearing Dungeons".
Grind Boss Keys on Boss Island and farm the Knight repeatedly. Shibuya Station also spawns 3 easier bosses every 5 min.
Return to the Dungeons NPC. You'll now be able to spend Dungeon Keys to enter themed challenge rooms.
Rune Dungeon drops Runes — gear you couldn't equip before. Clears also level up your Rune mastery.
Unlock Dungeons, grind the Rune Dungeon for drops, equip them from the Rune tab and level them by repeating runs.
Farm the Vampire King, aim for a 4.40% drop and route the rings into Ascension 4 / 6 or the Vampire King fighting style.
Track the Sailor Island temple timer, grind Jinwoo for 7% Dark Ring drops and trade into Ascend II or the Solo Hunter sword.
