Answer specific itemization questions yourself using data explorers!
Sites like https://www.metatft.com/explorer and https://tactics.tools/explorer are useful for looking up answers to basic questions, particularly around itemization. For example, What is the best item to build on Zeri after rageblade?
You can look up item combinations, artifacts, traits, and basically anything you want. It's a very powerful tool and can answer almost any lategame board question.
We recommended you adjust the rank/sample size filters to remove less reliable data.
Pay attention to "place change" or "delta" columns, but account for playrate. Generally the highest playrate items with good delta are best.
Keep in mind some items heavily rely on a specific combination (nashors tooth with jeweled gauntlet)
Create advanced queries to explore data on any aspect of TFT. Add Units, traits and items as filters then run any query you like.
