This is a screenshot of me doing it with my warrior that has no aoe dmg spell so I'm only doing it with 3 trial accounts.
If you were to do this with lets say 10 trial accounts and a mage with arcane explosion you'd be getting 10 times as much obviously.
With the changes to Fire-Water's Oath you are now able to kill players anywhere to get coins. But what you also can do is kill is level1 characters and still get the 10% chance getting a Bloody Coin.
What you need:
1 main account - for killing to get bloody coins.
1+ accounts - to make level1 that will get killed. (2 accounts = twice as fast, 5 = five times as fast etc).
_keySpam (_keySpam: Timed Keys Sender v1.2) (or similar)
What you do:
Buy the Fire-Water's Oath on Timeless Isle.
Have your character from the main account move to a starting area of the opposing faction. (In my case my horde character moved to Dun Morough, Dwarf/Gnome starting area.
Get on your 2nd account and make a level1 of the faction that you will be killing with your main character. (Dwarf in my case).
Make this macro on the account that will 1) Release spirit. 2) Talk with Spirit Healer and resurrect.
/target Spirit Healer
/run RepopMe()AcceptResurrect()AcceptXPLoss()
Put this macro somewhere on your bar. (In my case on "3").
What you need to do now is to go into your Keybindings and find the "Interact with target" keybind, and bind that to a key. (In my case J).
Next step is very important to make it automatic:
Enable "Click-to-Move" in your options (Interface -> Mouse -> Check Click-to-move, so when your character presses "Interact with target" it will move to the spirit healer.
Now you're almost done, time to start up _keySpam and make a short Loop of keypresses.
On the main account I have a loop that simply spams a spam-able ability to kill off the level1, in my case "Throw" on my warrior as well as presses your Fire-Water's Oath to keep the buff up while you're afk. (in my case I put throw on "3" and Fire-Water's Oath on "2").
On the 2nd account:
I use a loop with my two keys "3" and "J", with a sleeptime of 500ms between clicks.
When you start these two loops you should be having your maincharacter spamming one ability, and automatically killing the level1.
Automatically using the Fire-Water's Oath every 10 minutes. (600 seconds).
And your level1 should automatically be releasing spirit, interacting with spirit healer making him move to it with CTM, accepting spirit res, and then repeating this endlessly.
Links to my two scripts to use with _keySpam here.
Spam 2 and 3 on main account.
Spam 3 and J on 2nd account.
Now you can obviously set up more than one account that you release and spirit res on, you simply start another instance of wow on another account (easily on a trial account) and this will of course double your bloody coin farming speed, especially if you have a spam-able aoe spell.
