Just wondering what helmet everyone thinks is better for Voidwalkers. If anyone (for some reason) doesn't know the difference here it is: [b]Obsidian Mind[/b]: Nova Bomb kills decrease cooldown time for Nova Bomb. It became famous as the "unlimited Nova Bomb" exotic. [b]The Ram[/b]: Each Warlock melee hit triggers the life steal effect. This will allow you to run life steal + surge or soul rip. This helmet also has boosted armor value.
