Do caster out of combat options matter?

[Mastikator]

Casting Fly, Teleport of Speak with Animals is an action at the table, though. And the DM will have to react to it.

If the DM wishes to ban Fly, Teleport or Speak With Animals, it is also up to them, but it is poor form to not inform players of that during session 0/during the campaign pitch.

So you agree with me. DM reacts to actions player take at the table.

Completely separate from DM preps as response to player having option on character sheet.
