The build calculator is in active development, so bugs may probably exist. If you find a bug, you can message me on reddit and I'll do my best to fix it.

There are also a couple of caveats you should be aware of:

Doesn't Account For Non-Stacking Items: Some items have effects that don't stack (e.g. Journey Boots). The build calculator will happily add all these attributes together (because it's not that smart), but in reality only the highest of each attribute will be used.

Some items have effects that don't stack (e.g. Journey Boots). The build calculator will happily add all these attributes together (because it's not that smart), but in reality only the highest of each attribute will be used. Effect Inheritance: Some items inherit effects from their parents' (e.g. Warhorn). These won't be shown counted in calculations (perhaps this will be possible in a future version of the calculator).

While the build creator works on mobile, it's much easier to use on desktop
