Complete a task, then choose an upgrade
Open the equipment menu and inspect the relevant Arcana. Works of Mercy describe the actions needed to gain its Blessings; spend those Blessings on that Arcana’s Gifts. Tasks and Gifts are shown as separate lists below, not as fixed one-to-one pairs.
The reference covers 42 tasks for the 15 acquired cards and one task for the starting Cursed Flame: 43 usable tasks in total.
Read the condition, not just the number
A single cast, simultaneous targets and cumulative kills are different requirements. For a one-cast challenge, choose a group you can hit with the same spell instance. For a status-effect kill, the stated effect must deliver the defeat; a weapon finishing blow may not satisfy the task.
Exploration and collection tasks are different again. Five maximum-HP upgrades means five complete upgrades, not five fragments. Four matching fragments form one upgrade; keep HP and MP requirements separate.
Combine tasks with your next destination
Before entering a new branch, compare its enemies and collectibles with your current tasks. Weapon-family collection, room exploration and combat objectives can often be considered during the same visit. The linked directories help locate relevant equipment and rooms without storing your progress.
