As the title states, with this method you can add around 6-8k to your Healing Done for any arena. Use...? Make you look good if your healing alot as a melee?
When your Arena pops, simply mount up and fall so you take a bit of fall damage, rinse and repeat untill you are on about 500hp+ and then enter. On entry to an Arena you are automatically healed for whatever HP you don't have by the game, but this actually contributes to YOUR Healing done, and therefore shows up as Healing Done on the scoreboard.
Not the most useful thing around, but using this method and whilst playing my rogue, i can rank up a 9k Healing Done on the Scoreboard, and that is in a fight inwhich i recieve no Lifeblooms, Prayer of Mendings, Use a bandage etc.
