Patch 1.0.5 for Diablo III will fix a bug that has been discovered with the Trail of Cinders Rune which allows it to deal five times more damage than it actually should. So those of you taking advantage of it should enjoy it while it lasts.
“In patch 1.0.5, we will be fixing a bug with Trail of Cinders that is causing the rune to deal five times more damage than intended,” Blizzard community manager Lylirra explained on the Battle.net forums. “As a result of this fix, the amount of damage done by Trail of Cinders will be reduced from its current value (1500% weapon damage over 3 seconds) to the value we originally designed for 1.0.4, which is 300% weapon damage over 3 seconds.”
“We recognize that some builds which currently use Trail of Cinders will no longer be viable once this bug is fixed. Ultimately, we want to continue to provide players with more build options and ways to feel creative with their skill/gear selections, but not at the expense of going against our design goals or creating situations which can encourage players to limit themselves defensively.”
