Ruined King - EXP Exploit - Easy/Safer Method
17Okay, so here is the explanation :
As you collect the statue pieces you attack every enemy on their own. Get them as low as possible. Flee from the fight. Repeat with every individual enemy you intend to eventually fight in a group.
Enemies REMAIN at the HP you left the fight at but it does not contribute to any exp loss when you eventually take them all at once. You will get insane over kills / triple kills every time. Even if you accidentally kill some of the group a few times, as long as all three don't die, you will be okay. As close to sub 360 without killing any is ideal.
360 or less was a guaranteed kill from Ahri with only her base runes using power lane ignite move. MF or Yasuo might be better, was just working with what I had.
When you do the big fight, all of them are already one hit from dying. Make sure you don't use a dungeon ability to initiate because it may kill some and that will nerf the exp. I tested it out already. Took me a little over 20 minutes with some mishaps and bad decision making. I'm not sure if it stands to save the heroic route time but it should make all the fights WAYYYY easier and more consistent to get the EXP bonus on. I was able to get instant level 30 every time.
