Ars Omega is using Magic Clay and Lily of the Valley for a Glyph called Poison Flower. Recommend that Filter: Monster recipe be changed to something monster related, maybe a bone, spider eye or rotten flesh to avoid this conflict.

What version are you on?

The toxic properties of lily of the valley were actually the reason I chose to associate them with monsters, and I was actually the first to use them.

I actually chose flowers as the selection component of filter glyphs initially to avoid conflicting with other mods, so I'll have to talk to the Ars Omega dev to figure this one out. To some extent TMG and Ars Omega already clash, in that the power scaling curves conflict, so this is also a good reason to bring it up.
