The distant one

The amulet features a large blue stone and appears otherwise uninteresting. It's true purpose, however, is to disable any hostile technology D encounters, allowing him to approach the defences of vampires without immediately being shot down by computer guided weaponry. It additionally allows him to gain entry through similarly guarded doors; essentially all technology will see him as an ally and allow him passage and safety. The stone glows with a bright light when it is activated.

A longsword with a slightly curved blade. It's seen a lot of use and is well-worn. There is nothing unusual or particular about this blade. D replaces it several times throughout his travels.

Like Batman it's full of gear D uses, including caltrops, wooden needles, a micro computer, capsules, knives, etc.

Essentially slim needles of unfinished wood about a foot long. D throws them at speed for staking on the go.

A tiny, very high powered computer. Rare to see in D's world, it's capable of analysing chemicals, DNA, and other data. D also has several small cylinders for taking and uploading samples into it.

A cylindrical travel lamp approximately 6in x 2in. It provides light and heat, has a built in thermostat and can be opened to use as a refrigeration unit... somehow.

A number of small iron balls with spikes, can be used on the ground to slow down prey or pursuers, or thrown.

Like, several knives. For stabbing.

Used in various traps and other tricks, the thread and wire are as fine as spider silk and extremely durable.

A first aid kit holding all manner of items to treat injuries... except it's been so long since D bought it without ever needing to use it that the contents have expired.

A number of small capsules that contain freeze dried blood plasma and nutrients. D adds them to water and drinks them for nourishment. While they are a common source of food for dhampirs, they are very difficult to come across and have to be purchased from the black market or from a less than scrupulous doctor.

Large enough to cover a group of people, resistant to fire, water, cold, electricity, and heat.

Why does he even work for money, we don't know.
