As a monk levels up, the monk table says they get the following:
\begin{array}{|c|c|}
\hline
\textbf{Level} & \textbf{Proficiency Bonus} & \textbf{Martial Arts} & \textbf{Unarmored Movement} \\
\hline
\text{1st} & \text{+2} & \text{1d4} & \text{-} \\
\hline
\text{2nd} & \text{+2} & \text{1d4} & \text{+10 ft.} \\
\hline
\text{3rd} & \text{+2} & \text{1d4} & \text{+10 ft.} \\
\hline
\text{4th} & \text{+2} & \text{1d4} & \text{+10 ft.} \\
\hline
\text{5th} & \text{+3} & \text{1d6} & \text{+10 ft.} \\
\hline
\text{6th} & \text{+3} & \text{1d6} & \text{+15 ft.} \\
\hline
\end{array}
Do I add what it says at each level to what I already have?
At level 6, do get add +14 to proficiency? And also, if I started with 30 speed, do I add the movement as well to make my movement be 85 total?
Best Answer
The table lists the bonus you have at that level. They are not in addition to the previous levels.
So for a Level 6 Monk, he would have a proficiency bonus of +3, a Martial Arts die of 1d6, and a unarmored movement bonus of +15 (45 ft total).
Note: For a multiclass character, proficiency bonus is based on total character levels not individual class levels.
