Mimic

Mimic (なりきり士 / なりきり師) is a recurring job class and concept in the Tales series.

Job Characteristics
A mimic has the capability of using costumes to take on the powers of that costume's occupation. Oftentimes, the base character class is weak and capable of very little but physical attacks, but the characters they can turn into provide the mimic with versatility. In the games that they are featured in, they are the base costume but can usually be combined with other items or costumes as stepping stones.

Trivia

 * In Tales of Berseria, a set of Dio and Mell's clothes is one of the expedition treasures. Laphicet and Rokurou Rangetsu ponder if these clothes would give them the power of a mimic but eventually figure out that they have no functional way of testing their theory as testing it would involve taking the clothes off once more.
