I was thinking Gunblade with Fratmogs at first but I'm not entirely too sure how to approach itemization with his kit. Do you build AP or do you just need the health% on the Q? How are Wits End and Sunfire Cape on him?
Played lanewick for a while now, here's my general bruiser build:
core: boots, glacial shroud, spirit visage, botrk. After this you can pretty much do what you want, I'll usually upgrade to frozen heart and go from there depending on enemy team.
Start boots 2 health pots 1 mana pot
first back usually get sapphire crystal (i'll get this because more mana = more sustain and damage) and upgrade boots (ninja or mercury depending on team), wards
upgrade to glacial shroud or get spirit visage (depending if facing ad or ap). Get the other next.
Get botrk, go from here based on your team and enemy team. Get more offensive stuff if your lacking damage, upgrade to frozen heart if facing heavy ad, get frozen/guardian/warmongs if playing tank/initiater, maw against ap, etc.
