Did some clamming today for the first time. Want to add some items to the list.
I found Oxblood, Titanictus shell, Lacquer tree log, Maple log, and petrified log (3). Also noticed a pattern to getting bucket busters. Seems every time I found an item that npc'ed for more than 1k gil I would get a bucket buster on the next item dug unless I turned my bucket in immediately. That happened at least a dozen times during the day, (Yeah I know I'm a slow learner.) The only time that didn't happen was when my bucket had enough room to hold the heaviest item. That time I got the petrified log on the first dig after the bucket change. Next item was the lacquer tree log so I went and cashed in even though I still had quite a bit of room left on that bucket.
The good drops come mostly in the 100-150 and 150- 200 range.
All the new items in this list are 6 ponze items.
