I haven't done the next part yet, but apparently there's a fourth exercise available. Basically, do all of the steps above in the same order, except you only touch the summoning font once at the beginning, and the only summoning flames you touch are the fourth in the circle library. Have a rogue with you to quickly steal from the final summoned mob for a codex entry.
