Players will no longer need to wait for Molten Core to open before they are able to craft Devilcore items.
The community discovered the patterns drop from King Most in Un’goro. Shortly after the discovery was made, Blizzard pushed a hotfix making the patterns require Core Leather, which can only be found by skinning Core Hounds in the Molten Core instance. As of the 19th of July, https://www.wowhead.com/classic/item=17012/core-leather was replaced with https://www.wowhead.com/classic/item=7078/essence-of-fire, which can be farmed from the Fire Elementals in Fire Plume Ridge.
