I dont know if this was stated in one of the posts in the 130-odd pages of posts, but I noticed while reading the main post concerning Nether Protection that perhaps the fight where Nether Protection is almost invaluable is Hex Lord Malacress. Having a 30% chance to proc, while getting hit by multiple sorces of shadow damage every second, you will notice you will have some of the highest survivability rates during this encounter, and higher DPS than many other channeling casters or casters not using an abundance of instant cast spells, since while Nether Protection is active, Spell Pushback caused by Spirit Bolts does not occur.
Just my 2 cents
