They still seem pretty Ki hungry.
Assuming that Ki still replenishes on short rests, Monks may need to hire a Mercenary Bard.
They have more Ki than in tabletop.
At 5:59, you can see that the monk has 3 KI points.
He is level 2, which can be confirmed by the hitpoints he, and the companions have (17).
He should only have 2 by raw, and since it only shows current KI points (goes to 1 and 0 when he uses his abilities), that might suggest KI points are just doubled
