The fourth attack is guaranteed to

 critically strike, dealing 15 / 20 / 25% of the target's missing health bonus physical damage. The fourth attack will still

 critically strike against structures, but deals 44% reduced damage and doesn't apply the bonus physical damage.

Hopefully I got this math all right. Let me explain this. Me & my friend were having an argument over who is stronger. I decided to do the math. I don't understand what's the reduced magic dmg on jhins flower so I just put max & min. The characters have max lv stuff with infinity edge since the both scale well with crit. For xayah I used her q & e & for jhin I used his w & his e.
