Groot Canal Achievement
Interrupt a Charger with Groot's Call to Action.Chapter 10
There are actually multiple enemies that qualify for this achievement, with the first being in Chapter 10 (the enemy pictured in the achievement image is a Wendigo from Chapter 13, who also qualifies). The enemy pictured below shows up multiple times in Chapter 10.
As with all of the achievements for interrupting an enemy with a specific character's Call to Action, you need to weaken the enemy and fill up their Stagger meter. The best abilities to stagger enemies are Drax's abilities and Quill's Eye of the Hurricane ability. Once they are staggered, you will get a prompt while looking at them. Do so, and one of your allies will do a Call to Action. You unfortunately have no control over which ally attacks, so if it isn't Groot for this achievement, you can reload your checkpoint to try again.
