The spell Sanctuary says that the spell is broken if the subject attacks. It also states that the subject can use "non-attack spells" without breaking the spell. What I'm confused about is what exactly counts as a non-attack spell.
Clearly, a spell that needs an attack roll (say, Scorching Ray) counts as an attack spell. I'd guess that any spell that causes damage would count as well, though I'm less clear on that point. What about spells like Command, or Calm Emotions, which can be used to gain an advantage in combat, but are not actively hostile? What about Murderous Command, which doe not damage and doesn't require an attack, but is clearly hostile in intent?
