At level 75 slayer, you can now kill Gargoyles. These are a very good way for money. If you have 75 slayer, or a wild pie and want to attempt to kill these, you need: high defense bonuses(barrows or bandos is suggested for a long trip), good weapon(whip or godswords), super sets(optional), food (lobsters+), and tele's. Gargoyles are found in the chaos tunnel north west of edge bank. As you enter the dungeon, gargoyles are right there, so before you enter, pot up if you want. There are 4 gargoyles in this dungeon,and they are not very crowded so i suggest you use them. They drop granite mauls, and rune full helms. I made about 400k a trip with one maul and the rest in rune full helms. I hope this guide helps you kill gargoyles. They are decent money but with all monster drops, it can be random which leads to bad money.
