This is part of the set of quests which convert your https://vanillawowdb.com/?itemsets&filter=ta=1 Dungeon Set 1 gear into https://vanillawowdb.com/?itemsets&filter=ta=2 Dungeon Set 2. In every case, the quest starts from https://vanillawowdb.com/?npc=16013 Delina and is called https://vanillawowdb.com/?search=An+earnest+proposition#quests:0+3+1+2 An Earnest Proposition. Because the upgrade quests are available to all classes on both sides, there are actually 18 quests with this name (9 classes x 2 ""sides"").

The quests are rather involved and require a significant amount of travel to complete. In some cases, you will require groups to complete the associated dungeons or the summons in Silithus. Although 8 of 8 pieces of Dungeon Set 1 are not required to start the quest, it is proposed that the Dungeon Set 1 bracers are required to begin the quest chain - the other pieces of Dungeon Set 1 can be collected along the way.

Dungeon Set 2 is, in appearance, recolored versions of Dungeon Set 1.
