Having played DOS2 before, the Embassy in Arx was always annoying because cursed fire would get stuck in walls making it hard to stop cursed revenants from respawning on death.
DOS2 Definitive Edition has changed the mechanics of cursed revenant which has me stumped. On death, they spawn a small fiery pool on ground called "Infernal Ego" which after one turn will turn back into a new cursed revenant. These pools are low HP but marked invulnerable the same way Shriekers are and I have not found away to eliminate them. They cannot be source vamp'd, nor does Bless help. Similarly the revenant cannot be source vamp'd, and using bless or blessed water arrows on them will weaken them and remove their necrofire effect, but they still spawn ego on death. This occurs even if I have eliminated necrofire on ground from area.
Are we meant now to just ignore revenant damage and just charge through rooms to the portal, or is there a way to deal with the Ego things that I have overlooked?
