Chaotic is midcore, in case you were wondering

[Yeol]

From my experience most people want to have a go at something harder than the usual normal mode, but aren't willing or able to commit to the amount of time it would take to learn something as difficult as savage. Half-savage would be good.

You just described extreme trials.

What's interesting is that not all Extremes are designed equally. Some Extremes are easier than Savage, while others are as hard as the first or even second floor of Savage.

Savage itself is also not consistent with difficulty. Sometimes the second floor is harder than the third.
