Slippery Slick the fractal Instability and Thunderhead map mechanic

[Rico.6873]

I get why the fractal instability was a bust, but I find it odd that the Slippery slope wasnt made into a mastery and use to explore new paths

Like hot had chak poison which you could survive with the right mastery

A mastery could have been made gain a edge when on the oil or when things are getting slippery, so you can use this mastery to reach new places

[Khisanth.2948]

The poison mastery is one of the worse masteries(although the dubious honor of being the worst would have to go to itzel leadership, exalted purification and nuhoch proving). HoT already has too many filler masteries. It doesn't need more.
