Most items with useful information have their stats displayed in the tooltip when hovering over item icons in your inventory. Items will begin collecting stats when they are picked up.
To reset the stats, right click on the item, or enable the setting that resets stats when its item stack count changes. Change config ingame with either ItemStatistics_reloadconfig or RiskOfOptions.
For multiplayer, host needs the mod for clients to see stats. There should be no issue if someone is missing the mod.
After the end of a run, stats are outputed to the log.
The mod is able to credit the parent of a proc chain, but only if they apply a flag to the damage. So chain items such as Atg and Ukulele will be able to maintain accuracy in a proc chain. However items that do not flag their damage will not be credited by their proc children. These flagless items include all on-kill effects and items that create their own damage such as Tesla and Shuriken. DoTs will never credit their parents. So the more widespread your damage is, the less accurate to damage tooltip will be.
