Lore for Friday - From the Campaign Setting Rokugan (Oriental Adventures for AD&D, 3rd Edition, and 4th Edition). Kensai - Kensai are a martial class who "seek to perfect their weapons technique to the exclusion of all else. They are deadly in combat, but cannot use magical weaponry because it detracts from the appreciation of their skill."
I like some of the interesting flavor factions from older versions of D&D. In the current 5e environment, this tradition is actually ported over as the “Path of the Kensei” tradition. It does not prevent the PC from using magical weapons, but it does allow the monk to choose several weapons at different levels and considers attacks with them to be magical if they train with this tradition.
Have you ever played a monk with this Monastic Tradition? If so, what did you like best or what did you find the most challenging about it?
