Solo Duty: When it Rains
Follow Alisaie and use multi-target attacks on the sin eaters that you encounter.
When you reach the tower, go around the base of the tower and kill all the surrounding sin eaters, then go back to the south side of the tower to where Y'shtola is fighting. Pull all of the sin eaters close to the large winged sin eater. A blue circle will appear under it, and the other sin eaters will be killed if they are standing in the blue circle.
Afterward, follow the others and kill all the sin eaters that you encounter.
When Thancred and Minfilia separate from the group, follow Alphinaud. There will be a cutscene.
Use multi-target attacks on all of the sin eaters until the Forgiven Hypocrisy appears. Pull it away from your allies. When the three tethered Forgiven Venery appear, kill them quickly. Stack in the stack marker when it appears. When the tethered Forgiven Venery are gone, keep attacking the Forgiven Hypocrisy and ignore the other enemies. You don't need to channel aether to Alisaie.
