How can a sorcerer escape binding?

[pathfindernovice]

If I'm reading the spells right, can a sorcerer cast Mage Hand or Spark to escape ropes without an Escape Artist check? It seems Mage Hand might not need a somatic component in this regard since the spell says only you point a finger. Spark says "V or S" So can you just burn the rope as an unattended magical action? (albeit, very slowly by targeting the fibers?)

Hard to say. It technically does no damage, it just ignites fine objects as if you were using flint and steel. So the real question is if you could light a rope on fire with flint and steel? I'd say leaving a caster alone bound up in ropes for 10+ minutes will certainly allow the caster to burn his way out of some normal hemp ropes one way or another. But if the caster is being watched, I'd say definitely not.

Any way to escape manacles?
