Fixed the passage "...one of your open hand..." to "...one of your open hands..." as corroborated by Demiplane's page for the spell.

For the future, Demiplane (nor Nethys and any other 3rd party) is not sufficient corroboration. They can be wrong too! In this case, this looks like a Paizo typo that Demiplane took upon themselves to fix. This is obvious enough that we can probably do the same though.

Edited the title into imperative case. PR titles should complete the sentence If merged, this PR will ____ which lets the title be used directly in the changelog without the person preparing the release having to go see what the PR actually did.
