Nullify

Spell effects
Nullify removes most magical effects in the playing field that are cast by players and creatures. The Magick does not differentiate between friendly and hostile effects; it removes all of them. Nullify takes effect immediately but the casting wizard requires 1 second to recover. The following is a list of things removed by Nullify, but this list is not exhaustive:
 * Mines
 * Barriers
 * Storms
 * Shields (including self-shields)
 * All summoned minions
 * Active Magicks (including those that cause status effects)
 * Active beams (that are being channeled)
 * Magical projectiles
 * Queued elements in the spellbar
 * Most spells cast by Grimnir and Assatur
 * Status effects
 * Immunity auras

The following are not removed by Nullify:
 * Imbued weapons
 * Projectile spells and Push being charged

Pros

 * Counters most Magicks and spells, destroys enemy minions.
 * Has a very short combination sequence so it can be cast quickly.
 * Cannot be countered.
 * Useful in getting rid of blocking mines, barriers and shields cast by "helpful" team mates.
 * Disrupts enemy spellcasting by emptying their spellbar.

Cons

 * Does not remove immunity auras, even the temporary ones cast by wizards.
 * Disrupts allied spellcasting, removes shields from allies, destroys allied minions and stops allied beams that are active.

Trivia

 * Nullify is used by Vlad.
 * Nullify is incredibly useful against Death, Grimnir and Assatur.
