If Dredge Line deals the killing blow, it will drag Nautilus to where the target was upon death, as if the skill had hit terrain.
Titan's Wrath and Riptide are excellent farming tools when used together, as they each deal a good amount of area of effect damage.
Titan's Wrath resets your autoattack timer, so timing it right after a basic attack can allow for a quick second hit.
If you are farming minions, Staggering Blow can be a great tool to increase your last-hitting capabilities due to its free bonus-damage.
Be careful when chasing an enemy under the turret with Dredge Line. If you miss and hit the turret, you'll end up horribly off position.
Be sure about your position while using Riptide. You must be close enough to catch the opponent because this spell is pretty slow in animation.
The range onDredge Line is a bit further than the indicator shows. Experiment on terrain to see how far you can be to proc the skill shot.
Dredge Line is a fantastic method of travel, especially at higher levels. When running around between lanes, use it on terrain to pull yourself along faster. The same goes for fleeing; if a fight goes bad, run for the nearest turret or open terrain, and pull yourself to it for a quick escape.
Mark squishy/high priority targets with Depth Charge in order to give your team a good chance to kill them. It's also useful for stopping channels, such as 卡特琳娜的Death Lotus. Also, the squishy targets tend to be at the back their team so you'll be able to hit their entire team with the pass through damage instead of only one target with the explosion damage
Remember that Staggering Blow is an immobilization, which means it does nothing to stop channeled ultimates.
