This is where you can post topics relating to making money with combat. Copy and paste the form below when posting: (Items in brackets are tips.)

Method: [What is the title of your method?]
Combat Level Recommended: [What combat level do you recommend?]
Food? [If so, what type]
R/Ma/Me: [Ranged, mage or melee]
How-To: [How the method is done]

Example:
Method: Killing chickens
Combat Level Recommended: n/a
Food? No
R/Ma/Me: Any
How-To: Kill chickens in Lumbride and grab their feathers, along with raw chicken they drop (either cook or sell).

I have one of my own to start off:

Method: Flesh Crawlers and Zombies, Oh My!
Combat Level Recommended: 65+
Food? Bring 5 rows of salmon or tuna, possibly only one or two rows with 80+ combat.
R/Ma/Me: Melee
How-To: Wear full rune and kill the flesh crawlers and zombies. Pick up all steel arrows, body runes, coins or uncut gems. If you have a lot of inventory space, also pick up any iron ores, which are a fairly common drop. Bank with the Explorer's Ring (teleporting to Varrock afterwards) or in Edgeville. I have made 12k+ per trip down there, as I am now. Random Events are also common and are a chance to get miscellenious items, or just choose the GP.

Method: Lesser Demons At Karamja
Combat Level Recommended: 75+
Food? Swordfish/tuna/lobsters can be fished and cooked (see here)
R/Ma/Me: Any, though food is only needed for melee (safe spots)
How-To: Bring 30 GP & a full inventory of food to Port Sarim, then go to Karamja. Run north up to the volcano and enter it. Go out to the peninsula and kill the lesser demons. You can range from any space with an opening one square wide, since the demons take up two squares. These places are also places to go to eat after kills if lower-level.
If wanted you can bring nature runes and a fire staff to High Alch steel drops, which are pretty common. This is easier than banking, as you can convert them into coins without having to sell the individual items.
