I was wondering if there was a list somewhere, of must have items for a 120 tradeskiller. Obviously thinking of the pack pony and goblin, and garden, and "Proof of the Pudding" but what other items or quests are good to have under your belt. Thanks.
Both Planes of Prophecy and Chaos Descending questlines should be completed for their rewards. You get a really strong tradeskill familiar, an 88-slot inventory bag, and the summoned harvesting bag that acts as a 7th inventory bag but just for harvests only. PoP's storyline is also really cool. Blood of Luclin and Reign of Shadows don't really offer anything that was useful in VoV-- the Shadowed Staff of Luclin was needed to just help obtain the rarer-than-rare shadowed harvests, and that mechanic stopped when VoV came out. VoV's tradeskill mount is current best in the game. Not an absolute must-have, but certainly not bad.
Have you looked at the list of tradeskill gear here? Some of the stuff in the original posts has changed, but if you read through the responses in the thread you'll get updated info.
