Craftsman Timeline includes tradeskill quests at tradeskill levels 20, 35, 45, 55 and 60. They are all gained from your crafting guild's Tradeskilling Factions headquarters, from the Trades Coordinator NPCs (with Grandmaster in their names). The timeline is a part of Tradeskill Timeline.
The quests include:
- Journeyman Service (20) - harvesting in the T3 zone The Thundering Steppes
- Tradesman Service (35) - crafting
- Advanced Tradesman Service (45) - crafting
- Advanced Journeyman Tasks (55) - talking to a NPC in the T6 zone the Sinking Sands and crafting; harvestables can be bought.
- Senior Crafter Service (60) - harvesting and collecting items and objects in the T7 zone Tenebrous Tangle and crafting
Starting from level 20 and all the way to level 80, you can also do City Tradeskill Tasks Quests (another article: Tradeskill Writs) that will earn you tradeskill experience, personal and guild Status points and money.
