I'm submitting this on behalf of redrum who gave me permission to submit it for him.  I happened to have it from an old winuo project.

It's an excellent little script that works really nicely.  I've used it for ages.  It is great for treasures of tokuno, pink scroll farming, silver farming, and when used in conjunction with a looter, various other types of farming.

All credit for this script goes to Redrum and anyone he credits in the credits section of the script.

This is useful information for various purposes useful to folks here.

Items that block recall spots, and pathways but do not decay:
Some rubble(in testing to find a trend)
Full red soul stones
Some old items do not decay, as a result normal blocking items may fit.  To date, I have found a table of each type that did not decay. Many were labeled "of exceptional quality," however many with that tag decay normal.
