Why should the shots leading up to 4 have the same value as 4?
4 is perfect. 3 is almost perfect. 2 is half way there. 1 more is all he needs after the third.
So with this in mind, the space-time continuum should fold proportionately to cause every shot to be the fourth shot, and the fourth shot should deal 100% max HP true damage and pierce all shields and invulnerability statuses.
We should also request mods to move this to GP&B. We're almost literally doing Riot's job in this thread.
That is until someone on your team attacks the enemy you're after and you 3-shot them instead
WRONG BOARD SO I GET TO TELL YOU NO BAD IDEA LAUGHING FISH! GO BACK TO MEMES AND GAMES
wait league of legends is a meme
Better idea. If Jhin lands all 4 shots of his ultimate on a target, the 4th shot deals 444% max hp true damage (screw shields/heals saving them) and a rose blooms on the dying player's screen before going grey.
And yes, 444% because it's on the 4th shot, so four 4's.
This could work just so long as he needs 4 seconds per shot.
