The Dagannoths in the tunnels attack with range. Their max hit is very high which means you would be torn apart quickly. It is highly suggested you use prayer potions.
Now, I got a task of 171 Dagannoths, went and killed each one of them in the Chaos Tunnels. At first, I went un prepared, so my drops from the 10-20 kills in the trial run are not alched or pc'ed. I have provided both the inventories though.
Route -

Inventory -
5 Prayer Potions - With 70 Prayer, I didn't need more than 5 prayer potions to kill off these 171 Dagganoths
Super Set
High Alching runes - essential
Fighting Familiar - Since you'll be praying, healers are of no use. You could carry a beast of burden if needed, not recommended though.
Lots of empty spaces - essential
Important drops -
Fremminik Helm - An untradeable object, but these are the ones that pay most of your money back. Alch these for 3.9k each. These fall under the category of "Very Common" I guess.
Fremminik Blade - Another untradeable object, alchs for 3k each. When I first got it as a drop, thought it was a godsword
Freminik Shield - Alchs for 3k (roughly).
Warrior, Berserker, Farseers, Archer helms - Rare drops.
Ranarrs
Stretched Hide - 4.3k each
Circular Hide - 13.7k each
Flattened Hide - 7k each
Hides drop frequently
Trip result -

Note: The inventory pic to the right is from the trial run. I left around 5 fremminik helms (got like 6 in the 20 kills) on the ground as at that time I didn't bring alchs nor did I know their exact value. To the left is the inventory after I finished my task (all tradeable items in screen window and all untradeable alched which only left me with some money I forgot to put to price check and the charms)
I used 1 prayer potion in the trial run, with 3.5 on the second run, which comes up to a total of 24.5k (roughly). You can count 2k-3k for the super set (Don't take a super defence, I had only taken for the trial run being ignorant of the attacking styles). And take another 4k for an Ice Titan Pouch.
The total I spent was 31.5k. The money I received is 151k + the items in the inventory picture(had left some on ground).
I received 38 Crimsons, 14 Gold, 11 Green, 1 Blue for 171 Dagganoths.
The number of charms isn't that great, but compared to lighthouse dagganoths which mainly drop gold, I'm sure which one you would prefer.
These often drop pieces of fremminik clothes like capes, gloves and shirts, leave them. Also leave the seaweed and the edible seaweed. Leave most of the herbs except ranarrs.
These provide more slayer xp (85 hp), more combat xp than the light house ones.
For armour, I wore bandos with whip. I managed with 5 prayer potions with this set up. You could wear pray boosting armour to save more prayer pots than this if needed.
---
While killing them, alch all the fremminik shields, helms and blades you get. Collect all the hides and spined boots and gloves. Put all these to sell on ge. All will take some time to sell except the circular hides which sell directly for 13k each.
Sincere apologies if someone already posted this method.
Thanks..
