Expert Tips

Death Sentence (Q) hook reactivates to dash to the target. Always reactivate with second Q if you land the first.
The Box (R) walls slow through. Separate carries from their tanks with your box placement, cutting the team in two.
Dark Passage (W) lantern gives shields and pulls an ally. Use it to grab your ADC under a tower dive, not as opener.
