Your unarmed attacks show a master’s skill.
Prerequisites
Improved Unarmed Strike, character level 3rd.
Benefit
The base damage of your unarmed strike increased to 1d8 (for a Medium size creature). At character level 10th, this increases to 1d10 base damage.
Special
If you are a monk or other class that gains increased unarmed damage based on your level, you instead add 4 to your effective class level to determine your unarmed strike damage dice.
