Water Lung (Su): An air-breathing target can breathe water or an aquatic target can breathe air. This lasts 1 minute. If the witch uses this hex on herself, she can maintain it while she sleeps, allowing her to safely sleep underwater.

Just wondering...how often can the hex be given to other players? It does not say it is once every 24 hours like most hexes do. It does however seem balanced that a witch would have to reapply it every minute to keep it up, limiting other actions.

It appears to last 1 minute with each use, and can be applied any number of times to any number of creatures.

Seems like there is no limit to the amount of times it can be used on other players. There is precedent to this: Ward Hex.

A witch would lose 1 standard action out of every 10 keeping it active on 1 target, all the way to keeping it active indefinately on 10 targets by spending all her standard actions all the time.

I was thinking split hex... to make it more efficient. But I seem to read it like everyone else does. Thanks for the input! :)
