This achievement is story-related and cannot be missed. This will unlock pretty much at the end of the game, when you go back to fight Ivy in the botanic gardens. The best strategy for the fight is actually a pretty simple one: jump from left to right and mash like crazy to throw batarangs. Be careful not to step in any of the roots/grass that's growing underneath you because that will deplete your energy like crazy. You will hit a checkpoint after the first half of the fight.
For the second half I recommend doing the same. Don't focus on the goons, keep evading and jumping and throw batarangs.
