Examples? If anything DID contain an item, you'd use it like any other usable item, by clicking it.
That would make sense wouldn't it.
Problem is thats not the case. If you actually go to the site Sir Elmstyle
, and click on the crafting tab and scroll through the items. It shows the effects.
For one example in particular the craft item distillate. In this site it says that it is useable and "contains an item". And they have descriptions both on the site and in game, that are much like clues on how to unlock said item. For distillate it mentions fire. So for poops and giggles i tried firefighting with it equipped and nothing happened. I only did it for one hour though so who knows.
These items are:
Field cook: Liquor, and Cake
Tonic Peddler: Idol, Distillate
Saddle sack: Branding Iron, Unaligned Compass
Blacksmithy: Lead figurine, Soft marble
Is this a bug in the site? I don't know
Would that make some of these seemingly useless items....well more worthy? Yes
It is interesting.
Please look for yourself. I really didnt want to type this long reply.
