Even though this is extremely useful in Normal Mode for the Diamond Pack and Supreme Pack, it is not recommended to get for Corrupted Alchemy at Extreme mode as it requires 7.5k Gold, which will be hard to recover once you do get it; it also requires Topaz, which consumes 1 TU. Not only that, it will cost 50 Golden Temples when this is only ten times stronger than its prerequisite.
It currently doesn't have many uses until Enticing Darkness and above.
