General Discussioncaptain, how can i play core windranger?

mid, null talisman bottle phase maelstorm dagger aga
max powershot then ss

I am prob not the best to be giving out advice, BUT

a little tip if youre new, is to use windrun if youre being targeted in teamfights. it makes you immune to right clicks essentially. Also good for tower diving and first bloods.

u definetly want to start with null for extra damage to lasthit/harass in lane

then bottle for sustain

then phases for even more rightlick damage

then dagger or force staff for some mobility

then depending on the enemy team adjust rest of the items

if they have qop/storm/etc get orchid

if they have something like pa or troll get mkb

mjolnir aghanims is really good in most of the cases too

desolator helps with pushing and soloing rosh

sure i think null is very good early games then into bottle into phase into mobility
but how should i use the skills? should i constantly spam powershot then bottle-crow? i once see dendi did that but not really sure or should i spam shackle shot to harass and even looking for a chance to kill?
if i can't bottle crow, how much mana should i keep while farming creep? keep 1 powershot to push the lane when the rune minute mark comning or keep 1 shackle + 1 powershot to constantly looking for a kill?
thanks for u guys's comments

nulls into bottle

pshot waves and control runes when they're pushed out

use windrun to trade hits and go aggro on oppo

dagger is a must cos you're unlikely to land shacks be it laning phase or out of it

otherwise get a forcestaff if you're up against a clock

don't get a mek cos you won't have mana to sustain unless you get ab

midas is pretty much a must (depending on how well/greedy your team is) cos wr falls off pretty easily after the midgame

for core go mael for efficient dps and transition into an aghs/bkb depending on your oppos

most item builds are situational

@Dian 340 wr games :O

i really think mjollnir is bad. maelstrom is enough, the attack speed isn't worth it.

Thats how i go

If mid go null tango or 2 branches and ask for 1 tango for rush bottle
bottle>brown boots> ur winning mid in term of lh and ur team wont need u soon or u got fb go midas if not phase then midas> force/dag depending on there heroes>maelstorm> here its situational u can go from scythe or daed or orchid or scepter> scepter if u didnt build 1 > situational , bkb is good on wr so if they have too much disables get it.

I go for null > phase boots > orchid > blink dagger > optionals

ty for the comments :)
the last question is i want to learn what time to do what? like once valkiss teach me how to play slark: first 10 min just go offlane then try my best to survive while looking for some lh or sometimes even kill on enemy carry/sup. next 10-15 min i should roam more i bit and looking to clear the enemy jungle if possible.after that, the game is pretty much done. i always try to follow his word so my slark go quite well. i know there is not any formular to win but some kind of plays are quite good in most cases.
now can some guys tell me what to do minute-to-minute with wr? i'm still super noob and retarded so please be clear
