01

Choose the spell job first

Decide whether the grimoire is clearing rooms, controlling space, or converting a boss window into burst. That choice determines which Staff branch and tablet line are worth keeping.

A spell build that has no answer for an empty room can look impressive in a clip and still fail in a real run. Test the loop before adding more scaling.

02

Wisdom and empty-slot scaling

When a route rewards open inventory or Wisdom investment, treat those cells as part of the build. Do not fill them with a low-value item just because the grid looks unfinished.

Capture the number of open cells and the upgrade state when testing so the recommendation remains reproducible.

03

Hard Mode spell loop

Keep one low-cost cast or defensive reset for crowded rooms, then reserve the high-value spell for a priority target. The loop is successful when it survives the room between two boss windows, not only when the boss health bar moves quickly.
