Bonuses from multiple martial arts stack?

Just created a martial arts based character. The character knows tiger kung fu and karate.

Do the benefits of +1 dodge on successful attack still apply to my character if I’m using tiger kung fu actively to fight?

Martial arts bonuses do not stack. You can only have one “active” MA at a time.

Check your Keybindings page to find out how to access the Martial Arts selection screen. I believe the key is _ but I don’t know off the top of my head.
