Probing for traps is really pretty simple.
First, you need a trap probe. You can buy the recipe at a vendor and make one. Or you can buy a trap probe from a merchant (if another player is selling one).
I recommend learning to make your own – crafting can come in handy.
When you enter a building and come across containers (door, boxes, crates, gates – you name it), you may need to probe for traps. Even though the container has the line ‘Probe for Traps?’ – you don’t necessarily need to. You could risk it and just open the container… or not.
To use your probe, just click the ‘Probe for Traps?’ link. The screen will update and tell you if you found a trap or not. If the container is trapped, you’ll defuse the trap and gain XP. If the container is not trapped, you’ll be advised.
Containers can become trapped or untrapped at any time. The ‘World Master’ can decide to trap anything as he wishes 🙂 So always have a trap prove handy.
Traps probes come in a variety of sizes. Basic probes have 10 uses, some have 25, 50 and even 100 uses. Crafted trap probes have better durability.
