What spell from Harry Potter is used for water?

Answer 1

This is only really addressed in Harry Potter and the Goblet of Fire during the second Triwizard task. When Harry is underwater his spell that normally creates a spark comes out as a "jet of boiling water". But I'm sure different spells would look different.

Answer 2

Pretty much the same as it does on land. Of course there are some spells that are useless underwater, Incendio fo example.

Answer 3

Instead sending sparks like usual spells do, casting them underwater sends a jet of hot water.

Answer 4

Probably the same.

Answer 5

You can use the wand under water.

Answer 6

Augimenti. :D
