In addition to the above, the ToS team announced that the Swordsman is the next hidden class. Called Nak Muay, the Swordsman will arrive in game on February 20th.
"The combat style of the Nak Muay is very different from other kinds you may know. We attack the enemy with our hands, feet, elbows, and knees. The risk of injury is high, and it is not an easy style to learn. No matter how strong you are, you must never underestimate your opponent. If you do, the Nak Muay technique becomes nothing but a means for violence." - Khanom Caolaw, Nak Muay Master
