So one instability per level.
From the live stream we saw one that makes meleeing a bit harder, and they mentioned there was one that made ranging a bit harder. So this could potentially make it that some groups could have an easier time with scale 50 then 48 (hard to say til the update goes live and someone has the time to get up there)
So why can’t we get an option to add challenge for ourselves by adding extra instabilities?
In an extreme example, allowing the people that enjoyed challenging themselves at scale 80 to challenge themselves at scale 50 by using all 19 current instabilities.
This could also be a perfect way to attach titles to fractals instead of just “complete ## difficulty while doing X and/or in Y amount of time” it could be something “complete ## difficulty with 4 extra instabilities (5 total)”
