The artifact of glass is extremely useful for a lot of achievements. It makes Bandit's second achievement trivial, and the Engineer's and HAN-D's both really easy. It also helps with the Commando's, Miner's, and Mercenary's because it lets you clear groups of monsters in single bursts without risking damage while your abilities are on cooldown, but they're still challenging.

Worth noting:  damage to a Guardian's Heart shield does not seem to count against the Commando's second achievement, but DOES count against the Miner's.
