Hi all. I was wondering if there are any way for me to achieve the 2 goals below?

1) A state which allows a character to take no damage for X amount of turns and when the last turn ends, the character will receive all the damage while s/he was in that state.

2) An item mix skill. Much like Rikku's from Final Fantasy 10.

Well First, post a mock layup of what your looking for (Made in like paint or something)
and Second, Then somebody might be able to help.

Have a great day!
