I'm a bit of late starter but tonight I started training Imbuing on a human crafter. Tonight I used 22 Fire Rubies to gain (using Petra's Training guide) from 40.0 to 41.0??? This is insane!!! Is this really how Imbuing gains? Failures 50% of the time? An item that takes 3MA to imbue unraveling to 1 MA? Or am doing something terribly wrong?
