This guide will let you know how to awaken Dough and unlock the Dough raid chip.
First, you must have 10 cocoa and one chalice, then trade with a guy for a sweet chalice. You must kill 500 NPC and activate the mirror behind rip mama. When it’s done, make sure the person with the chalice is the one who talks to the NPC. But it is not sure if this is required since the update is still new. Letting the person with chalice talk to rip mama to activate the mirror will be better.
Then you will be teleported into the mirror world with doing, defeat him. You will obtain a red key; use this key to open the door to the candy castle. You permanently unlocked the NPC to purchase a dough chip.
