Evelyn doesn't know

‘Why didn't the trap chest work as it was supposed to?’ Evelyn thought she knew these kinds of traps can sometimes be unreliable due to the biological nature of these classifications of traps as one time a friend of hers, a female reptilian woman once purchased a trap treasure chest from a local magic shop and it cost a good chunk of her money. Though, when she used to trap other adventurers instead all she got was a sleeping chest snoring loudly like the elephants of the Wild Lands. Not only did Evelyn's friend plan fail to rob other adventurers but she was soon caught and punished by being tied up in a pole in the middle of town without a stitch of clothing to cover her naked body making it to oogle at by men from the town.

Evelyn was smarter than that instead of purchasing the trap treasure chest from a local magic shops she opted to buy it from the Black Market as it became a reliable source of traps and potions that aided her in the numerous adventures of theft during the lifetime. Plus, Evelyn tested the trap before utilizing it on the field. So it was safe to say that her plans would come into fruition. Although, with the female mage arrival said otherwise. Maybe that mage had a potion enchanted on her preventing traps to target the mage, or maybe the mage knew that the chest was a trap and decided to cast a spell on the trap to prevent it from eating the mage. Questions like that traveled through Evelyn's head like arrows to come up with a rational answer. Those questions were put on hold as she heard soft footsteps of boots from the entrance of the ruins.
