Probably the tankiest (I've got 489,732 base hp) and most annoying build you can go up against. IT. WILL. NOT. GO. DOWN.
The 735k is calculated by 490k times 1,5 since you have the overheal - it's pretty much the tankiest build in the game >.>
If you're really tired of Pred, I've found that this is a really good counter for that. It's honestly a pretty great counter for most sets lol, have fun abusing it!
