One of my old projects which I sadly did not finish, sharing for educational purposes, it's not complete tool.
It was mostly based on Wizatek's ItemAll Editor, so credits goes to him too.
@Karmel0x was helping me in that time with it too so I guess I should credit him aswell.

• Optimized L-Chaos Texture reading class, added old file (Version 4) and DXT5 support, added texture flags viewer
• Optimized L-Chaos Mesh reading class
• Added async support to MySQL class
• Icon Picker
• Model Viewer Tab - Item equiped class and standalone model (needs to be HEAVILY optimized, its straight copy pase)
• Effect Helper Form - shows which Item Skill Monster Title is using an effect name
• Item Drop Data Tab - shows which monster drops current itemid with their position on the map (dungeons not supported, map writing function was writed for testing purposes so I would look into optimizing this one too)
• RareOption Picker
• Database Connection Settings are no longer in binary mode, changed to JSON
• SMC Viewer/Editor
• Added sorting types - Name, Description, Type, JobFlag, Flag
• Flag is no longer bugging (most of item tools I've saw was reading it as uint32 instead of 64)
• All Flags/Types are listed in ENUM

• Whole Crafting Data, Static Bloodseals and Fortune Data tab but it can be easily implemented thought
• Logs are not implemented
• ZoneFlag picker is not implemented
• Effect picker is not implemented
• Export to L-Chaos item lod file is not implemented
• ModelInformation form is not completed, the idea was to get all textures from actual displaying model in DX panel and show its data/flags and rest data here
• Effect.dat reader, I've already started writing it on cEffect class

• Here is compiled version
