Wild Surge Table

When a Wild Mage casts a spell, there is a 5% chance the spell explodes in a wild surge. A d100 is rolled and the resulting effect is applied. Higher rolls are usually better than lower rolls.

Additionally, the Wild Mage's effective casting level fluctuates ±5 levels from his true level on every cast.
