Illusions

[James the Newbie]

Looking at how this spell can be interpreted in game terms, based on what all you people have said (thanks for commenting by the way... even if you made horrible horrible puns)
'if you can count it as a single object, creature, or force, you can go ahead and make it'

and I think each game table needs to come up with a strict definition of what counts as an object, or have various examples outlining it.

Personally I like 'if its all physically its one object'

You could have 'if its all based on one theme' its one object that seems to have been raised a fair bit

If you like a lot of freedom at your table, ruling that you can create anything you can think of seems like a fairly fun mechanic

If you like to be incredibly stern the only 'object' you can create is a fundamental particle...

Agreed, it's going to be up to the DM, and will vary from game table to game table.

Players have a long history of trying to rationalize their way around rule limitations, and DMs have an equally long history of deciding when and where to say "no".
