blizard + thunderstorm
it might require spell might to be active also...not sure.....its also a really good way to kill yourself and party if you aren't careful....
Shockwave - Crushing prison + force field.
Improved Drain - Vulnerability Hex + Drain Life or Mana
Flame Quencher Grease Fire + Blizzard Grease Fire is eliminated.
Storm of the Century Spellmight + Blizzard + Tempest Increased lightning damage with a larger radius. Eliminates the Blizzard effects (i.e. knockdown and freeze).
Shattering Petrified/Frozen Enemy + Critical hit/Stone Fist/Crushing Prison Instant kill (higher levels can resist)
Paralysis Explosion Overlapping Glyph of Paralysis + Glyph of Repulsion An instant, large radius, long duration paralysis AOE. Both the glyphs are consumed in the process. Friendly fire is possible.
Nightmare Sleep + Horror The target takes heavy spirit damage, but the sleep effect is lost
Improved Drain Vulnerability Hex + Drain Life/Drain Mana Drain Life/Drain Mana do 2x the damage.
Entropic Death Death Hex + Death Cloud Truly massive spirit damage
Shockwave Force Field + Crushing Prison Damages and knocks back everyone except force-field target, very hard to resist. (Enemy target only - Works if casting Force Field on an ally that has Crushing Prison)
Advanced Reanimation Spell Might + Animate Dead More powerful skeleton with special abilities
That should be every spell. Enjoy^^
