Do you mean the message that says "Creature damage partially dodged" ?Same issue with the dodge %. It's listing it at .xx% dodged instead of xx.xx%.
100% dodge basically means you've moved out of the creature's range or view frustum. The message is the "Creature missed" message.Also I do not know if its possible or not, but can you dodge 100% of the damage? If so, can you list that when it happens in combat?
