let's make this into guild shirt 

It is time

Doom is kinda vice versa , depend on what your teams need , since he can farm loads of items very fast .
Usual doom , carry with heart and AC + wolves aura .
But I don't suggest Doom with scepter + dagon 800 .
My usual doom items build , Phase Boots ~ Midas ~ Meka ~ Dagger ~ Shiva ~ BKB ~ AC ~ Heart
Items should always changing depend on the situation , as you can see my last match doom with Hex + shiva + Refresher , enemy team is like WTFBBQ is this , double doom double hex double shiva proc , Team fight = WIN .

Depend on situation , if you need an early meka than Midas , just skip the Midas .
Cons for Doom : Low armor , means right clicker will kill you in no time (Meka : adds you some armor and stats points and additional 250HP recover when click it , and a stout shield will do some damage blocking for you in early game . ) Low Mana Pool ( You can't spam LVL death as much as you can if you devour creeps that much , so in later game I get shiva for boosting the mana pool plus armor ) Tips : Get an early Soul Ring if you really needs to use your skills that much . For me Phase boots > Arcane Boots for Doom , since doom only needs those mana for devour creeps , Doom hero , Lvl death to do some damage to hero and last that HP Regen + movespeed + DPS Lari Api skill .
If you don't know why doom run so fast when that skill clicked , try to walk on the road without wearing shoes on afternoon .
Cute Ranked match with Gotchu and my friends. Yoshii-kun LOL

Clock very nice hero , on early + mid game but not so good if late game .
Scepter is a must get items on Clock I think , that 12 scd hookshot is wicked sicked .
Stout shield > Shoes(Can choose between phase/tranquility) > Urn > Wood magic Sticks(not really)/Bottles > Rush for scepter .   
Try to move around and gank after getting boots and Urn , get smoke + TP .

If you are farming quite well, midas is a bonus. If not skipping Midas is also a viable build as his devour is basically a free midas for you. Most dooms will be jungling but I still prefer laning doom unless team has heroes which need levels fast.

So midas is not a must. All items in Dota is situational. Different in most games.

offlane is the hardlane or u should call it suicide lane

the lane which is not near to your jungle.

radiant = top lane
dire = btm lane
