Traps
The Rogue can detect and disarm traps. Hunters use traps. Disarming an enemy faction hunter's trap will flag the rogue for PvP.

Footlockers
A number of areas in the world have footlockers in them. These areas are in place for rogues to visit to increase their lockpicking skills. The contents of these footlockers are only token amounts of treasure, but they should allow for a more interesting experience while increasing lockpicking skill. The difficulty of the locks in the area correspond to the level of the zone, so if your lockpicking skill is around 100, you would go to Durnholde Keep in Hillsbrad. But if your skill is 250, you might head to Tyr's Hand in Eastern Plaguelands. The Rogue trainers will point the player to an appropriate area with boxes to unlock depending on the lockpicking skill of the player.

Profession Options
The Rogue can choose whatever trade skill he or she wants, however these skills might be useful:
Enchanting - Rogues can enchant their equipment to make themselves more powerful.
Herbalism and Alchemy - The Rogue can create buff potions or healing potions.
Fishing and Cooking - The Rogue has no healing so the class is dependent on food when no healing party member is available. Fishermen fish up locked boxes which can improve the Rogue's Lock Picking skill.
First Aid - First Aid is a good profession for any Rogue to pick up. It limits your reliance on the healers of your group, as well as reducing the downtime between each fight.
Skinning and Leatherworking - Rogues can create their own equipment and sell it to others as well.

Poisoning
The Rogue has the unique ability to create and apply special poisons to weapons. Poisoning can be trained at level 20. To create poisons you will need to buy empty vials and purchase various reagents as dictated by each recipe. At higher character levels the Rogue can train in more powerful and unique poison recipes. There are even additional extremely powerful recipes to be found which require rare ingredients available out in the world. Poisons can be resisted.

Crippling Poison, which can slow an enemy's movement speed, is very effective against monsters that run when they are about to die. This makes the Rogue very useful in a party. Party members become accustomed to having a Rogue around for this helpful ability.

Lock Picking
You can improve this skill on locked chests. You should also create practice locks with engineering, or purchase them from engineers, to develop this skill more quickly.

You can also offer to unlock locked boxes from other players for free to build up skill in Lock Picking.

Only rogues may train in Lock Picking.
