My favorite Item in dota would have to be the ring of basilus. Its made up of a sobi mask and a ring of protection. It can be bought at the start of a game if pick a character and leaves you with 103 gold to either buy something to heal or to restore mana too. The ring gives you and aoe mana regeneration and defence. I find it really usefull because i find that i like to cast spells early game to get early kills.
What is your favorite item and why?
