How to unlock Gastly

To add it to your League, complete its challenge — trigger 600 elemental reactions in a single run — then weaken and catch it when it appears in your next run.

League challenge1 step
  1. Trigger 600 elemental reactions in a single run.
    Goal: 600
  2. Catch it in your next run.
    After the challenge is complete, Gastly appears in a run. Weaken it and catch it — it only joins your League once it is caught.

"In a single run" goals must be met in one run; the others add up across all your runs. League-size goals count the partners you have caught.
