Class Description[]

Where others might revel in fame and glory, the Spymaster abandons their identity, hiding behind many masks to accomplish their goals. They immerse themselves in their alternate persona so flawlessly that they can even copy the abilities of those around them.

Mirror Trick does not include the cost of the ability you copy. In other words, you can copy Consumables used without lowering your stock of items, or copy abilities with high MP costs without spending any additional MP.

Shadowstep functionally gives the character Flying.

Pandora's Box is weighted to use abilities that match the character's ATK and MND stats. In other words, if you have high ATK, you're more likely to see abilities based off of the ATK stat. If you have high MND, you're more likely to see abilities based off the MND stat. The normal MP cost of the ability copied is disregarded, and no MP will be spent.
