My advice for DoL collecting is to make a routine schedule.

1. Red Scrips - Most people will alternate between Chysahl Greens and Adamantite Ores. Red Scrip fishing is rather tedious and unreliable. The rest of the Red Scrip items will require Folklore tomes which require 99 blue scrip tokens. A hell of a chore but some of the items you can get are useful.

2. Blue Scrips - Lots of options. My personal cycle is Abalathian Mistletoe -> Morel -> Cuprite, since they appear in succession and are easy to collect.

To start you off aside from the guides posted before me, take a look at the node gathering clock and find a schedule that fits you.
