If you open your talents and look at unstable magic it says that Arcane Blast, Fireball, Frostfire Bolt and Frostbolt have a 20% chance to explode on impact but if you look on your armory it will say it's a 30% chance. I checked on the patch notes and saw no mention of a change and googled "last 30 days" and saw no mention of a change. Do you guys know which is correct?
