You can make over 3 hour long trips if you make Prayer potions and Antipoison potions from the drops. I camp these for Effigies, this wasn’t my Slayer task.
My setup for a trip:
9 Overloads and Prayer renewals, 3 Steel titan pouches, Holy wrench, Cannonballs, Steel of legend scrolls, Teleport to house (house in Pollnivneach), 1 Antipoison++ and 2 Prayer potions because it takes a while to get the ingredients for potions. I don’t use Herbicide because I am already 200M Herblore and it would be waste of space.
Keep your cannon at Cave crawlers while banking.
About 80K Attack/Defence/Strength and 180K Ranged XP per hour. You use about 5K-6K Cannoballs and 600 Steel titan scrolls per hour and get around 1 Effigy per hour, varies a lot though. Sometimes I have had almost 20 hours without Effigy drop.
Glacors and cannoning Ganodermic Beasts in Multicombat are also very good Effigies if you want Magic XP.
