Your build plan

For Rei, compare Tentacles of Chaos while keeping the recommended Build assumptions setup fixed. A weapon or set change is easier to judge when you do not also change the team and skill timing.

Equipment options

9 options

Start with equipment you can actually obtain. These are alternative recommendations, not pieces to equip together. Refinement, set size and team restrictions change the result.

Team examples

A lineup is a starting point: check that each teammate is available and that your team can repeat its resource cycle. Replacing a unit also changes buff timing and defensive coverage.

GACHABUILDS

Test your setup

Choose one option, run the same encounter twice, and change one variable. Record whether the next rotation starts on time and whether the team survives without losing its damage window.
