GW2 Kinfall Fractal - Shatterstep Achievement

Complete the Shatterstep achievement in the new GW2 Fractal Kinfall by avoiding the Cryoflash mechanic. This is done by recognizing two different variations of the mechanic. One will show a ball over the bosses head that raises upwards. This means the Cryoflash will hit anyone in the air. If the boss spins while there is no ball, then the mechanic hits players on the ground. When the mechanic occurs, you must decide whether to stand in or dodge the ice spikes to either be shot into the air to avoid the ground mechanic or to avoid the spikes to stay on the ground when the mechanic is in the air.
