DiabloZ is a search engine for Diablo 3 character builds.
It allows to find relevant builds easily, from keywords search.
Players can submit their builds through the character builder, using the official Blizzard's calculator then adding some descriptive text about their build.
A keywords system allows to insert links with tooltips for skills or items.
Here is a build example.
The stuff analyzer allows to load a hero stuff and compare each item properties with theoretical maximums, in view to identify gear strength and weakness.
