Deckard

A companion app for Diablo IV. Coming soon.

Deckard reads your loot, checks it against your build and helps you trade it for gold. It takes care of the parts of the game that aren't playing: checking every drop against a build guide, planning crafts and finding a trade partner.

Features

• Builds, item by item: paste a maxroll build guide and Deckard lays out every item the build needs, like the character screen.
• Gear and crafting: Deckard tracks how close your worn gear is to the build and what's left to imprint, enchant or temper.
• Skill tree and Paragon: follow the build point by point while you level.
• Reading items: hold Alt over an item in game and Deckard reads its tooltip from the screen, then tells you whether to keep it, craft it, sell it or salvage it.
• Stash sorting: hover the items in your stash and Deckard sorts them against every build you play.
• Trading for gold: players search listings by affix, see how each fits their build, make offers and post buy orders. Trades are completed by hand in game, for gold only.

Built to respect the game

Deckard only reads what's on the screen. It never reads the game's memory, never modifies its files and never sends input to the game, so it stays within Blizzard's rules for third-party tools.
