Unless you're casting a spell, then it does what it says in the spell description.
See the difference?
Yes there is a large difference in that the basic effects of the spell are prescribed in more detail than martial options. However that doesn't also preclude using spells in a similar way. Using invisibility to leave only one visible target, using an illusion to create an image of a racial enemy and so on. The more prescribed everything is, the more it becomes like button pushing or card playing. On the one hand you have something silly like using come and get it on an ooze. On the other you run the risk your DM saying that's too silly. I prefer things more fluid though. Most DMs want players to have fun. The key is try to apply some logic and common sense and just ask the player HOW it is they intend to achieve the result they want. Making a lot of noise by banging a sword on a stone floor to attract something with blind sense could work in some circumstances.
