I just found resurrection now in Death Valley in the Undead Lands. One of the necros is selling it. Also selling Armageddon and Demon Portal.

I think there is another post concerning the mass spells, maybe in Tips and Hints section. As others have pointed out, I'm just here to confirm that I too got Geyser from the Titan's Tear quest and have not seen it for sale (or via loot) since.

Anyone get the spells "Life Light" or "God's Armor"? These two are in the description of the mage skill "Healing" I haven't found God's Armor but I've got Divine Armor (translation thing?) as a quest reward from the guy at the beach in Valley of a Thousand Rivers. Haven't tried it out yet.

I got Life Light as a quest reward from the Tree of Life quest. This is quickly becoming one of my favorite spells as it heals 800 hitpoints to every mob in a 7 square grid for 10 mana at level 1! Best of all, it heals magic resistant units like Cyclops and Black Dragons! That's a full heal dragons for 10 mana!

Now, my core spells are Fire Rain (elven lands), Demon Portal (Demonis), Phantom, Kamikaze (Demonis), Weakness (Demonis) and Life Light (Elven lands quest).
