I have created this guide mostly for my own benefit as I couldn't find any where that had all the Sigils and effects listed. The descriptions are pulled straight from the journal with slight formatting alterations. If anyone shows some interest I may add more to it so feel free to leave a comment below.

Fire is a spell meant for direct injury. It is the easiest spell to build for doing raw damage.
