Bubble block

It traps your target in a bubble that can't be broken by force. It can only be removed when dispelled and is immune to any physical attack. Any magic user can do it however classes like fighters and rouges can't. The bubble can be used either as a shield or a trap however it takes 15 Mp and you can only have 5 up at max, or you start to receive two damage per second. It doesn't work on anything above level 6.
