This is a rolemaster sourcebook filled with lists and lists of wizard spells. It is one third of the _spell law_ sourcebook (3rd ed.) which is now out of print. The other two are _of channeling_ covering priest magic and _of mentalism_ covering psionics. It also includes the various wizard based rolemaster professions. It is useful for spell ideas for any system in particular, even GURPS or D&D and of course Rolemaster or MERP.
The spells are clear in what they do and easy to translate into other systems.
