Kill chaos druids, commonly found in the Taverly "members dungeon" a bit south of Taverly. They're also found in the wilderness, about level 2-4, in the members part of the Edgeville Dungeon. And yeah, runes are allowed. Melee is pretty hard. I did it at 75 combat only meleeing since I didn't have any runes are extra cash. And it hit high. But safing is the easiest way. And you can get a Dragon longsword for as low as 85K, or a DDP++ for as low as 50K. But it's common for 100K/55-60K. Oh, on Lost City, bring some food, since you have to kill Zombies until they drop a woodcutting axe and they might hit you. Can't think of anything else I'd add... oh! Fremennik Trials is good when you get 25 fletching, lets you wear Fremennik helms, perfect for combat. And if you really want a cat (I find them annoying) do Gertrude's Cat, I think it's quite easy.
