Illaoi, the Late Game Noobsmasher
Runes: CDR/Lvl Quints, Armor Pen Marks, Armor Seals, CDR/Lvl Glyphs
Masteries: http://efferentinc.com/wp-content/lol6calc/index.html#K0K0C1CvClv1Y
Items:

Skills: E > who cares what else
How to play:
Cast E, pull opponent towards you. Your base AD will be 145 * (1.25^6) = 553, but when the shield procs, that goes up to 691. Then, due to masteries, your abilities will do 5-15% bonus damage depending on enemy health and the number of champions you've killed. You will have 4600 life.
Test of Spirit will be a guaranteed kill on-cooldown, since 45% + (8% / 100 AD) means it will return between 90-100% before masteries, depending on if your sterak gage buff is active. However, your masteries increase that up to 94.5-103.5% pre-shield, or up to 115% when gage is active. E is going to be on an 8 second cooldown.
It's like a blitz grab that you cannot minion block and lets the team safely burn you down while you are powerless to do anything about it.
If someone survives the pull, then the tentacles spawn and kill them.
Say cheese!
