During the game you will encounter a few Phillak. These three horned, ram-looking animals can do a lot of damage and while attack when you are close to them. To be able to get this achievement, you will need to get the Evasive Kick ability in the Lightsaber Skill Tree,
Now find a Phillak. These creatures can be found on Zeffo, or in the Meditation training. Choose Meditate - Meditation training - Combat Challenges - Tomb of Eilram (it can be found in wave 2).
When standing next to a Phillak, wait for it to glow red and it's about to attack you, dodge and get behind the beast. Make sure you are close enough for the beast to kick you. After this happens, do the Evasive Kick ability (evade and action button).
Achievement unlocked.
