Leveling dungeons are dropped from low-level squad leaders and world bosses, offer superior equipment compared to the zones in which their entrances appear. Though equipment items obtained enemies and Treasures tend to drop at the dungeon's tier, those obtained from bosses and Big Treasures (when the damage threshold is met) tend to drop at 2 tiers above the dungeon tier.
Elder Game Dungeons
Elder game dungeons are meant to challenge players who have attained level 20 and have at least a full set of Tier 8 equipment. In addition to housing Upgrades, these dungeons hold Elemental (ELEM) and Ultra Rare (UR) equipment which cannot be found elsewhere.
