Treasure goblins are the best monsters to hunt as they usually drop valuable items. The Tome of Secrets are dropped by treasure bandits; seekers will generally drop the gems whereas the Pygmy are good for gear.
Do note that, these statistics are very rough, these may not apply to your game or area as nobody knows how valid it can go. At least it will tell you a little about the loot items and the enemies you should focus on if you’re broke.
