All three Crisis Fragments together open the Burning Monolith inside the Fortress to fight the Arbiter of Ash. The number of fragments per kill scales with Waystone Drop Chance: around 300%+ for 2 fragments, 750-900% for 3 (rare even then). Dying consumes the Waystone and locks the node.

0.5 added two new Citadel maps with two new bosses that drop keys to the Arbiter of Divinity. Walk in straight lines on the Atlas to expose fog and surface citadels faster.

Note
The +66% citadel spawn rate is still active, but it was introduced back in patch 0.3.1, not 0.5.
