Another, more reasonable example:

Caster with, e.g., an item of Create Monstrosity activates it, wants the monstrosity to attack the enemy immediately. Can the

monstrosity do so?

At the above example. Yes. Action limits are your main limitation here. You have to individually order these creatures to do things. Unless given conditional orders (that could be repeated), they do nothing... The copies would have the standing orders from the previous copy though, which could cause issues.

All of these scenario's encourage your GM to use the chapter 26 (page 282) rule allowing them to spend 100-200 DP on these creatures.
