singed for spycrab:

runes --
red and quints: combined total of 10 armor pen, rest attack speed
yellow: armor
blue: choice (cdr, magic res, more attack speed)

masteries --
21/0/9 generic
13/9/8 more sustained

skill order --
E/Q/E/W/E/R  R>E>W>Q

jungle items --
cloth + x5 pots -> razor -> wriggle/boots1

route --
minigolems -> wraiths -> wolves -> blue
gank or port (try not to give the enemies your blue)
buy a longsword and use rest on pots
minigolems -> red
gank if possible
wraiths -> wolves

clear the jungle as regular until you have wriggles, a wriggle and
one/two pots will be enough to solo dragon at that point.

item suggestions --

first item will always be wriggles

your boots will almost always be attack speed boots, alternative
is merc treads for cc heavy teams

next core item is brutalizer -> youmuu it owns it owns it owns

from that point on you'll be building items situational:

zeal/phantomdancer nice stats overall, but don't rush it
phage/frozenmallet give survivability and a nice slow
infinityedge is beautiful for damage output
bloodthirster has nice lifesteal, but get IE first
lastwhisper if the team is heavy in armor
bansheesveil for dealing with cc

there might be other viable items i haven't listed here so
dont rely on that 100%


TIPS:

-if they don't have a jungler/their jungler sucks ass don't be afraid to counterjungle

-once you're built up with some items, you'll be able to take on most champions 1v1 (assuming
that they aren't fed)

-don't forget to use your youmuu. don't forget to use your youmuu. bind the item slot to T
or something

-don't forget to use your wriggles, it owns.

-late late game, replace your wriggles with a better item.

-did i mention youmuus and wriggles own

-youmu and wriggle are also both cool touhou characters

-let me tell you more about wriggle

-Wriggle's appearance and name are both quite androgynous compared to other characters, so it used to be a point of some contention whether Wriggle was a male or female character before the release of full version, her wearing pants certainly didn't help either.

-Blue eyes, teal hair, bug-like antennae. Wears a white shirt with stylized short sleeves, a black cape (red on inner side), and knee-length blue baggy pants.

-don't feed
