Remake petrify post 2.0

[Alaltus]

Addition of gradual petrification.

Yes that version of petrification seen many times in the ff series, two kinds of petrification, gradual and instant two tiers in a way. Gradual would give you a timer and reduce your stats/slow your attack rate as the timer got closer and closer to 0 at which point you would become completely petrified. This gives players a chance to pre-empt the effect with a gold needle.
