Detection is a rogue ability learned via the [Glyph of Detection]. It is primarily for vanity, costing no energy and using the old detect traps visual (eg. "Swirly Ball").
Oddly enough, rogues can use this ability to see the two marmots, Sekret and Sikret, in the Room of Hidden Secrets in the Scarlet Halls. Normally they are only visible to players using the [Extra-Dimensional Ghost Revealer].
