Fool-The-Eye
This pidgin illusion is commonly used by traveling conjurers to avoid being killed by bandits, wild beasts, or other potential wayside troubles. Fool-The-Eye requires that the caster gesture continuously with one hand, presumably while dodging and weaving to evade attacks. As they do so, the caster’s form seems to blur and waver like a mirage. The caster can use his or her free hand for other tasks, such as counterattacking, but doing so risks losing the focus that maintains the spell.
For as long as the spell is maintained, the caster gains +1 to all defenses. Fool-The-Eye has a base difficulty of d6 and a base cost of one strain; for each extra point of strain taken, the bonus to Dodge increases by +1. All bonuses are doubled against ranged attacks. Taking actions with the off hand requires a Concentration check at d8 or the spell is lost. Increasing the initial spell difficulty decreases the Concentration difficulty on a one-for-one step basis.
