Spells in Harry Potter

My favorite spell would have to be Incendio. Purely becasue its fun to say..and how much easier would it make those camping trips where it rains every night?

Accio would be extremely useful...especially when you lose everything ..that reminds me where's my iPod...The worst spell to cast on somebody has to be either sectumsempre (for obvious reasons..what was Snape thinking when he came up with that one) or Crucio. At least when Avada Kedavra is used the person dies instantly without pain.
