Stack crit damage because this page is all about making Parrrley hit as hard as possible once Statikk Shiv, Infinity Edge, Muramana, Youmuu's Ghostblade, and Last Whisper are online. Armor seals and MR glyphs keep the top lane stable long enough to reach the first big crits.
Go 21 in Offense for the crit damage, armor penetration, flat AD, lethality, and execute damage that make the Shiv-IE-Muramana Q delete people. The 9 Utility points match the Flask plus Biscuit opening and help the mana-hungry Tear route get through lane.
Skill order

Corein buy order
1Tear of the Goddess700gBuy Tear because the one-shot plan needs Manamune and later Muramana damage.
2Cloak of Agility730gTake the early crit cloak to make every Parrrley crit a huge lane swing.
3Statikk Shiv2,500gRush Shiv into a squishy top laner for crit chance, attack speed, movement speed, and burst.
4Infinity Edge3,800gRush Infinity Edge to make every crit Parrrley hit absurdly hard.
5Sword of the Occult1,200gStart stacking Sword of the Occult once the damage is online.
6Manamune2,100gFinish Manamune because the completed mana item adds a massive amount of damage.
7Muramana2,100gUse Muramana for the big single-target damage, and remember to turn it on before going for the one-shot.
8Youmuu's Ghostblade2,700gAdd Ghostblade for AD, crit, cooldown reduction, armor penetration, and an active to chase kills.
9Last Whisper2,300gLast Whisper finishes the burst plan by cutting through armor.
10Elixir of Agility250gUse Elixir of Agility for the extra crit chance in the final one-shot setup.
Situationalonly when the game asks for it

Trinity Force3,628gBuild Trinity Force first instead of Statikk Shiv when the top laner is tankier, like Sion.

Youmuu's Ghostblade2,700gConsider Youmuu's before Shiv if the crit gamble feels too unreliable and you need steadier damage.

Doran's Blade475gStart Doran's Blade into Lulu top in the future for a stronger AD lane start.
Notes
the author's own wordsThe goal is simple: build enough crit damage and raw AD that one Q can take somebody from 100 to zero. This is a high-roll Gangplank setup, so the early game is about surviving the lane, taking the crit gamble when it is worth it, and snowballing hard once the first big crits start landing.
Against a squishy top, rush Statikk Shiv and then turn the lead into Sword of the Occult stacks. Manamune is only here because the whole build is trying to reach the biggest single Q possible; once it becomes Muramana, keep the toggle on before fighting or the one-shot is lost. Finish with Infinity Edge, Youmuu's Ghostblade, Last Whisper, and an Elixir of Agility for the full crit burst setup.
