Hello there, Thanks for the report. Ember of Char is intended to make Solar ignitions spread Scorch to nearby targets. We have also seen other Solar source-label issues before where explosions or ignitions did not count as the expected Solar source and therefore failed to trigger related Solar effects correctly, so this does sound plausible as a source-credit / tagging issue rather than expected behavior. If possible, please also include: whether this still reproduces in the current build whether it happens every time with Refraction Core ignitions, or only in certain activities whether Ember of Char works normally for your other Solar ignitions on the same build That comparison would help determine whether this is specific to Refraction Core, or part of a broader Ember of Char source-credit issue.
