Topic: Spell Clarification

Just finished reading through the spell descriptions of the Rules & Magic book, and I found a couple of spells that I would welcome some clarification on:

For the spells Creation, Minor and Major, both are practically identical and state that the items created last for the duration of the spells; but each has a listed duration of instantaneous. I'm guessing it should be something like 1 turn/level for the Minor version, and 1 hour/level for Major, or something like that.

The Earthquake spell also mentions an effect lasting the duration of the spell, which is also an instant one.

That's pretty much it; only minor. Oh, and there is no reverse effect mentioned for Locate Object, which has an * by the spell.

Loving some of the different mechanics for some of the spells, such as Bless and the complex and potentially deadly Summon spell.

Thanks
