Update: By inting, I dont mean inting from the start of the game.
I farm and chill, and be unkillable early, always shielding, never dying. I start Dorans and put about 3 points into w for early sustain as to not die, get gold, and sustain poke and trades.
On my first back, I'll pick up Dark seal, ryby crystal, and maybe an amp time and pots, since I out sustain and never die whilst having a gold advantage.
They enemy gets bored and ints for me, or my support will, and I just wont die. I'll stack seal up that way, while build hp heavy items. I rush Liandries, than go Sor shoes into Morellos, than Mallet into Warmogs and Steraks. With the pen and AP, I can survive mid game tower inting(tho I still let minions in first) and when Demolish procs, I use my Q to CHUNK hp out of the towers. The hp build and runes make demolish really strong, so combined with hp, ap pen, and a passive sheild, I can int towers come mid game, take them down, and get a double kill plus a ghost.
Than I move to the next tower. The AD from Mallet and Steraks makes the ghost compensate the damage I'm missing, thus taking a second tower down ez, as ghosts scale with total ad. By than the ghost dies, so me and my team rush the drake. With drake ghost, it can facetank towers without minions so I can straight up int a 3rd tower and demolish is up again. I get about 1k extra max hp with drake ghost, so you can imagine how much damage a drake shot+pen Q+Demolish will do to that 3rd tower.
With demolish and a hybrid hp+ad+ap build, I can int towers, take it down, and not worry about dying.
By the time drake ghost is down, my ult is off CD, so I back, rinse and repeat.
See how that works? You chill and farm early, almost unable to die, get early dark seal stacks while building only hp damage items for the exception of Warmogs, than after 6 just chain ghosts and int towers and dragons.
For sums I run flash and exaust.
Runes are Gaurdian, demolish, overgrowth, and chrysalis with magical footwear and the CDR rune.
This only works bot lane.
