Yikes. That's indeed a good way to draw attention. My brother made a unit of Orichalcum to bribe a Force 20 Spirit to please not edge against the oversummoning. Then he played Thor inside a Bug Hive. Lightning Aura Force 20...
And yeah, the special uses ended up in Forbidden Arcana with some tweaks, and they rock. iirc, FA also changes the whole 'spend 10 reagents to go to limit 10 as Force 6, or spend 6 to cap a Force 10 to 6 hits', instead allowing you to either set or boost the limit. (So it's 4 reagents to go from Force 6 to Limit 10). In return, reagents are capped in quantity, so you're encouraged to use a higher quality when it really matters.
