To get this achievement you need to pick up a Lihzahrd brick from the Jungle temple. There are two ways to break these bricks, the Picksaw pickaxe and the Drill Containment Unit mount.
The Picksaw is available earlier in progression and has a 25% (journey/classic), 33.33% (expert/master) chance to drop from the boss Golem. This boss is mandatory for standard progression and can be summoned with an alter found within the temple you're trying to break for this achievement.
