In a blue post today, Blizzard announced that they would be adding a hotfix to allow players to purchase Malefic Cores from MOTHER. You’ll be able to use these cores to upgrade the corruption resistance of your cloak up to the cap. You’ll still be able to earn up to two Malefic Cores per week until you are caught up to the cap by completing Horrific Visions and killing N’Zoth in Normal difficulty Ny’alotha or higher.
This is a welcome change for players who were stuck feeling like it would be impossible to play catchup if they missed out on cloak upgrades earlier in the patch on their mains, or for alts they want to start pushing more content with. I know I’ll definitely be taking advantage of the change to make sure my characters’ cloaks are maxed out!
Later today, we will apply a hotfix to the game that will allow players who have upgraded the legendary cloak Ashjra’kamas to Rank 15 to purchase Malefic Cores from MOTHER for 2,000 Echoes of Ny’alotha. This will be repeatable, up to the current maximum Resistance that the cloak allows (currently 92 Corruption Resistance, and next week this will increase to 95).
The intent of Malefic Cores was to provide ongoing incremental weekly power gains, to help overcome remaining challenges in this final tier of Battle for Azeroth. This has been similar to past systems in Warlords of Draenor (upgrading the legendary rings via Archimonde drops) and Legion (upgrading trinkets from Argus the Unmaker). While each extra bit of Corruption Resistance only represents a small increase in potential power, we understand the frustration of feeling weeks behind, especially without any controlled way of closing the gap faster. With this hotfix, players can further supplement their progress through the wide variety of endgame content that rewards Echoes of Ny’alotha.
It will still be possible to earn up to two Malefic Cores per week by fully clearing a Horrific Vision and/or defeating N’Zoth the Corruptor on Normal difficulty or higher.
