Summoned creature

Any creature that is created by a skill or effect, rather then a spawn or game script, is considered a summoned creature.

An abreviated list of summoned creatures:
 * Undead minions created by necromancer animate skills.
 * Spirits created by nature or binding Rituals.

Several skills treat summoned creatures differently:
 * Banish deals extra damage to summoned creatures.
 * Holy Spear, if hits a summoned creature, deals holy damage to nearby foes and sets them on fire.
 * Unnatural Signet recharges instantly if used on a summoned creature.
 * Swap can change your position with target summoned creature.


 * Signet of Ghostly Might causes allied summoned creature to deal more damage, but is destroyed after 10 seconds.
 * Signet of Binding causes allied summoned creature to gain maximum health, but is destroyed after 30 seconds
