You've accepted its offering and now better understand the multi-functional properties of Stasis. Eramis has used that same understanding to fortify her Fallen barriers and valued items with Stasis-enforced Seals. You can now unlock the simplest of her Seals: [Stasis: Glyph 0]. Search the area. There's likely to be one nearby.
Seals: [Stasis: Glyph 0] [Stasis: Glyph 1 Locked] [Stasis: Glyph 2 Locked] [Stasis: Glyph 3 Locked]
