I don't get this 'Shaolin' thing people keep bringing up.
If by Shaolin you mean, "He doesn't wear plate armor" which, yeah, he doesn't. He looks like he wears a combination of Cloth and Leather at the most. Which is quite apt for what the Class seems to be trying for.
If by Shaolin you, "He doesn't use weapons, he uses his fist," then, yeah. He uses his fists. We have an example of the Monk in this setting, and a lore example of how magic can be used. This Monk in the art obviously enhances himself magically to have superhuman attributes.
Though I'd note actual Shaolin Monks train with swords and other weapons as well (you can see some interesting video documentaries of it). I'd also just plain note that the Monk in P:E's art looks nothing like a Shaolin Monk. This is a picture of a Shaolin Monk:
The picture of the adventurers, including the Monk, for P:E, looks nothing like the above.
Well the Art we've been shown doesn't show them using Swords or Bows, and instead shows the Monk with fists sheathed in magical energy. Kind of speaks for itself what martial arts means in the context of 'this' Monk.
the monk in PE art has a sword/dagger tied on his belt if you look closely
