Hello Dota 2 comunity, can you guys give me some advice on how and where to put wards? I've never played with friends or teams and is always playing alone but sometimes I wanna put wards for my team but I don't know where to put them
any videos I can watch and learn from?
Also does "carry" means late game heroes and "support" is warding and assist hero?

Another question is how to get the black greevil? I have a rare egg and 3 red,3 blue,3 yellow essence but I don't really like the white pet so I don't want to open yet. Is the black greevil hardest to get? I heard is need shadow Essence but need 1 or 3

^

Thank god is only 1 shadow essence, my friend told me need 3
I will try to find someone to trade the shadow essence

Oh ya does bkb immune to Enigmas black hole or not?
