Thieves Tools are a required item for the use of Open Lock and Disable device skills. They provide a bonus to the skill roll ranging from +1 to +7 (Basic Tools provide a +1 bonus; Masterwork Tools provide a +2 bonus; magically enchanted tools provide an additional bonus from +1 to +5 on top of the Masterwork bonus). Their stack size is 1,000 in a single inventory slot.
Thieves' Tools are found in stacks of 50. You can buy basic tools from any General Vendor, and +1 to +4 tools from the Free Agents vendor after you acquire enough Favor. They can also be found in chests, bought from the Auction House, or constructed with Trap Parts.
Thieves' Tools have no minimum level which largely makes any Tools other than the +5 Tools irrelevant. As many traps will injure a character on a failed roll (and some chests are also trapped), any character wishing to use Open Lock or Disable Device should consider the acquisition of +5 Tools a priority.
Rusty Thieves' Tools also exist and can be purchased from Elspeth Wright after completing the The Lost Seekers (Waterworks) story arc. However, their maximum stack size in only 3, (not 1,000) in a single inventory slot. Rusty Thieves' Tools provide: Open Lock Bonus: -2 and Disable Device Bonus: -2 (the [-2] penalty is probably thematically due to their corroded state).
See the DDO information project for DC's of Traps and Locks throughout the game.
In a Device Workstation Combine a number of Mechanical Trap Parts and a weapon with the corresponding enchantment bonus (the weapon will be consumed in the crafting process) to create a set of 50 Thieves' Tools.
The Trapmaking Feat is not required for the manufacture of Thieves Tools. However, a character without the Trapmaking Feat will need to acquire the Mechanical Trap Parts from another character.
