One can cast Bones to Bananas on an inventory of Big bones (355) to turn them into bananas.
The spell cost 1 nature rune, 2 earth runes and 2 water runes. The staff of water removes the need of any water runes and the Mud battlestaff (members) removes the need of any water runes and earth runes. If wielding the staff of water set up one of your quick presets to withdraw 26 bones, 1 nature rune and 2 earth runes. For members wielding the Mud battlestaff this would be 27 bones and 1 nature rune. Cast Bones To Bananas, which will cause the bones in your inventory to turn into bananas. Open the bank, click the Quick Preset, and repeat. When playing at maximum efficiency, up to 780 spells can be used per hour, for 20,280 bones or 21,060 bones.
If positioned correctly it is possible to have the Quick Preset and the banker position in the same location, combined with putting Bones To Bananas on a easily spam-able hot key it has been tested that more than 10,384 bones can be made to bananas in the time span of 12 minutes and 30 seconds, which totals around 49,843 Bones converted in an hour, equaling a profit of approximately 5,901,500 wielding a staff of water or 5,964,400 wielding a mud battlestaff. Big Bones have a buy limit of 10,000, so if you intend to process larger quantities, you will need to plan ahead.
If using the Quick Preset hotkey "1", positioning mouse over bank, and putting Bones to Bananas on hot key "1", it is possible to cast 2,800 spells per hour. Tested on 47 casts per minute, and 484 casts over 10 minutes. Press the banker simultaneously or slightly before pressing the hotkey "1", and press "1" again immediately when bank is opened. The banker must be clicked as soon as possible after bank closes. This totals to 72,800 bones converted in an hour wielding a staff of water/earth, and 75,600 bones if wielding the mud battlestaff.
The Explorer's ring 4 gives a 50% chance of casting Bones to Bananas for free for up to 10 times per day, reducing the cost of this money-making method somewhat.
To maximise efficiency, add the Bones to Bananas spell to "1" on the action bar. Click on the banker, press 1, and 1 again, and repeat.
Members can use a mud battlestaff, which will remove the cost of earth runes and water runes and will use 1 less inventory slot that can be replaced for bones. This makes it even more profitable.
