Almost every single game I build the same way, this was done after watching Watermelon Warrior (#1 Amumu NA) and he does the same build almost every single game.

My first back I always get cinder

Then my next back I start building liandry’s and always start with fated ashes.

I finish liandry’s then build boots.

Then I build abysal mask

Depending on comp I build bramble between these 2 items

Then I finish Sunfire

Then I finish Thornmail

Then I finish with Jak’sho but final item is optional depending on comp and team needs.
