Disclaimer to avoid confusion: This post was written in 2016 and is no longer accurate. Cedar containers no longer slow down the decay of their contents any more than other containers do.
I wrote this based on my own in-game testing prior to being on the development team, and while the information was correct at the time, it no longer is, and has not been for quite a while.
Conventional wisdom dictates that cedar items decay more slowly, but that cedar containers do nothi
From a cursory look at the current Wurm Unlimited code, here is how it currently looks to me:
Cedar slows down decay, but only of the item itself, not contents.
Pottery amphoras still slow decay of contents.
Decay slowdown bonuses still stack.
The only current application of this is the "slowed decay of contents" rune. So for instance, you could have a runed satchel inside a runed raft inside a runed ship, I guess. Assuming you can put the rune on all those things.
