Red Death and the other named monsters are immune to the effects of Ethereal Voyage . Area Peace and Orange petals are quite useful. A well-trained Cu Sidhe is capable of killing any of the named monsters. However, the random spawn of assorted undead critters makes it somewhat challenging. The Tamer trick of standing on the same tile as your pet is less effective when the undead spellcasters use Necromancy area spells. Red Death is solo-able by a tamer with a Cu Sidhe and area peace. It is recommended to frequently use Gift of Renewal and Nature's Fury to take some of the heat off your pet. If you are targeted by an overwhelming number of monsters, run for the exit and re-enter the dungeon and try not to move: occasionally, the monsters act as though they cannot see you for several moments, usually enough for you to regain control. Don't be fooled by the cemetery gate. The named monsters on the other side of that fence can open in, teleport past it, or cast on you from inside.
