Expert Tips

Dredge Line (Q) range is your primary engage. Miss it and you have no engage — aim around minions.
Depth Charge (R) is a tracking missile. Lock it onto the carry as soon as a fight starts.
Your CC chain is Q hook → passive slow → W shield → E knockup → R. Land Q, then chain everything.
