Containers, Spell Types, and Circles

[OneShot]

My recommendation is to create terms to define the different types for ease of reference.

I suggested an improvement of terminology already here:

I like the content!

Spells "of first type" and "of second type" are excellent for discussing it.

But perhaps this classification could be rephrased in the later rule? Perhaps classifying spell containers instead of spells: "spell of first type" => "container for casting duration" or briefly "casting container", and "spell of second type" => "container for effect duration" or briefly "effect container"?
