First of, you basically always take the green pet. You can start on any buff, or solo on Raptors.
Lvl1 you take W, make sure to reset your auto attack properly with W, the AoE helps a lot with Wolfs and Raptors. Full clear unless a lane brawls a lot from lvl 1-3.
You´re quite strong in 1v1s at lower levels, Nautilus has high base damage and with Aftershock, shieldbash and cheap shot, your fairly tanky.
Your first buy is ALWAYS "fated ashes", you need it for clear speed, but make no mistake, you dont finish Liandries until thrid of fourth item.
Deadmans Plate and Abyssal Mask is generally your strongest 2 item core, but of course your build should be situationally changed.
Your ganks are strong, especially early, till end of laning phase for, your strong at forcing flashes, work with lane ganks and return ganks.
You´re very strong in Skirmishes and Teamfights, look for picks, or simply be present, as long as you have hook up, you´re a threat to most champions.

Objectives can be taken alone, although if you get caught solo on drake, it can be rough for you, if your team has Prio in lanes, ask for help.
