I am looking for an armor/weapon spreadsheet with data that includes dmg accuraty def and hp bonusses does any1 know where i can find such thing?

 

or a site that has all tiered item pieces noted.

You're going to have a hard time finding this information anywhere currently. The game keeps getting updated so often with tweaks and rebalances that its not likely anyone has really put much effort into that yet. However, If you had a specific item, or more information you were looking for that we could help point you towards that would be helpful
