This spell is a complete waste - why would anyone use it?
-300 damage for 5 ticks=1500 damage for 375 mana. This damage over time spell does not work with the spell damage increase effects on common cleric armor, i.e., Dakkamor's boots, which provide a (scaled) 45% damage increase for level 65+ magic based dd spells (all cleric nukes are magic based). This spell also does not work with the the Fury of Magic AA line (crit nukes) available to clerics. So, what the vast majority of clerics will get from using this spell (unless you have a rare focus item such as the ring that drops in the Ikkinz raid event) is exactly 1500 damage.
-Desolate Undead, the new 68 undead nuke, does 1560 base damage for 385 mana AND works with items such as Dakkamor's boots AND the Fury of Magic AA line. The net effect with AAs maxed is non-critting nukes averaging over 2k damage and crits over 3500 damage. For a whopping additional 10 mana, therefore, you get about an extra 33% regular damage and over double the damage every 5th or so cast when you crit.
The only real purpose for this entire line, beginning with the level 39 spell introduced in the Velious expansion, is to make a bunch of undead mobs unmezzable so you can wipe your group or raid.
I would have just deleted this spell when I received it from Karsor the Mad, but for the fact he would have given it to me again when I turned in my next 67 rune. It does not make me happy to spend hours farming to get a rune like this and be forced to accept this piece of crap spell as my "reward".
