Diva Intervention Eliza's signature ability says "50% of the damage inflicted by Sekhmet attacks is regained as health" But only attacks in Sekhmet Mode count towards healing Eliza, the damage done by Sekhmet blockbusters like Lady of Slaughter and Sekhmet's Bite don't actually heal her at all.
Either the description made a typo and it's supposed to say "Sekhmet Mode attacks" or the Sekhmet blockbusters are bugged in a way that don't count as damage done by Sekhmet.
