Demi-antithetical Complex Essences
When casting a spell using a Complex Essence/Deep Dominion essence and one of it's Demi-Antithetical Essences, the spell will be more difficult to cast and control than with compatible essences. The level of difficulty is based on the number of Demi-antithetical components, but should always be easier than a fully Antithetical pairing. Each Prime/Base essence type and the Deep Dominion/Complex Mana type page contains information on the Demi-antithetical Complex Essences associated with that essence type.
If compounds have one or more antithetical matches of their prime components, but not a complete antithetical match, then the compounds are demi-antithetical.
