You only need on chest if you set the macro up to lock it automatically after you successfully pick it. If you're starting at 30 then make a new character with 50 tink 50 carp and make one yourself. Then when you can attempt a gm made one check Adriel in the Vesper strip for a gm tinkered chest and that will take you the rest of the way.
