Summons a number of Faerie dragons based on the level of the caster.
Any forest under the protection of a faerie dragon is a calm and magical place, one best left alone if you're wise. Like the sprite, this creature is born magically, spawned by the forces of Nature from a clear pool of water.
As with the other level four summoning spells, this casts a fairly useful number of Faerie Dragons, though it is probably best cast after one or two rounds of casting buff spells such as Mass Fortune and Dragon Strength.
If you have a choice, which level 4 creature to summon is largely a question of personal preference and tactical situation.
