My very dear friend Mildred Farseer offers a Life Trap spell for 1 training point if you're a level 10 wizard. We usually play bridge together on Tuesdays and I meet her in her secret shop in Colossus Blvd. She is an excellent bridge player; she always seems to be able to look several hands into the future. Uncanny!
You can find the life trap spell on colossus blvd right by Mindy Pixiecrown. You will have to turn to the left if facing her and walk into the house. There is a trainer there for a few good spells. Hope this helps!
