NOTE: I timed combo 2: it is about the same as the normal E Q R W time. I would suggest only using it more as a surprise tool because people will not expect you to flash charm after your Q! If done a bit slower it wont give you the amplification on your Q but it will probably do enough damage if you hit the rest of stuff with ignite. A very good consistent outplay combo when you have flash and are on the offensive in Q range.

If you have any questions lemme know in the comments :D
Here is an example of the ringtail combo from a game 5 yrs ago when I first learned of it :    • League Play #1: Perfect Ahri Combo
