So for Halo the optimal usage is to be at max range (30 yards) out form the group before casting. For Divine Star you want to use it on the stacked group. But what about for Cascade? How do you get the most out of Cascade? 1 thing I do is precast it before massive AoE damage comes out. The tooltip says that it "grows in power with distance", does this mean that it heals for more the greater physical distance it travels? Or is that just saying it gets stronger as it bounces around more?
