Traplover (3.5e Flaw)
From D&D Wiki
If you see a Trap you have the urge to set it off.
Effect: You take a -4 penalty to Disable Device checks. If you are within 30' of a trap you know about, you are shaken until you personally trigger the trap or the trap can no longer be seen by you.
Roleplaying Ideas: You hate it when someone else triggers a trap.
