Sphere of Refraction
Version: Heroes 5
Level: Relic
Effect: There is a 30% chance that the enemy hero will cast positive spells on our units instead of damaging spells, directly opposite to the spells they were supposed to cast. For example: blessing-curse, fatigue-bloodlust, and so on. If the enemy casts a mass spell, the chance of reversal decreases by 10%. However, there is a 5% chance that our hero will mess up when casting a spell and will also cast either a blessing on the enemy or a curse on himself. Mass spells can be cast without fear. For mages, this artifact is even more useful: it increases the probability of reflecting magic with a magic mirror
