Dungeons & Dragons 5.1E — Monk

[thoroughlyS]

I like Abundant Step, but given that Monks have slow fall (I think you have them keeping their abilities that weren't listed) I wouldn't even bother with the gently float to the ground. If through whatever shenanigans they get super high in the air and slow fall can't cover the fall damage so be it.

This way they don't have to sacrifice their reaction.

Decisive Strike is a copy of Kensei's Unerring Accuracy so I would probably try for something else.

As mentioned above, in an ideal world I would rework the subclasses as well. The Kensei would get a different thing.

My last comment is that because of the change in Ki (more at early levels, less at high levels) you might want to readjust the ki for Empty Body. Spending 8 ki when you had 18 to use Astral Projection is one thing, spending 8 ki when you have 11 ki is something else entirely. Even the 4 ki to transform is a much bigger cost then it was before. Similarly ki hungry subclasses have been unintentionally(?) hurt by this ki change and would potentially need to be adjusted.

My change gives monks higher ki at all levels. At 18th level, you have 18 + WIS mod, not anywhere near 11.
