Fighter/4th

Improvement

When you reach 4th level, and every even-numbered fighter level thereafter as shown in the fighter table, your fighting capabilities evolve.  You gain one of the following improvements:

• Increase two of your ability scores of your choice by 1, or one ability score by 2.  
• Master one or two martial techniques.  If you choose to master only one technique, increase one of your ability scores by 1.
• Master a new fighting style.
• Gain a feat.

This feature cannot increase any ability score above 20 unless you have a feature that increases your maximum score for that ability.

Each time you gain this feature, you can also replace any one fighter technique you know with a new one of the same tier, in addition to your normal Improvement.
