Where do YOU use Spirits Within, Tempered Will?

[Jpec07]

So in another thread, I commented on how it seems like there are surprisingly few instances where Spirits Within seems to actually work as an interrupt, at least in my experience. Tempered Will also seems to not work half of the time, either. So I thought I'd ask other folks to see if there's anything I'm missing:

What enemy spells are you able to interrupt with Spirits Within?

What knockbacks and movement-impairing effects are you able to negate with Tempered Will?

Spirits Within

You can use Spirits Within on Mind Blast for A6S.

Succubus' first aoe attack
Elite Marks that use casts such as Mirka or Maahes

It's a bit outdated now, but Spirits works on the AoE paralyze attack from the blue golem in T9.

Tempered Will

Seph Ex knockback in Phase 3, Use Tempered Will before that and I can stand where my adds are going to spawn instead of having to run towards them from the edge.

A6 knockback from the last boss.
A8 Same as above when you fight him again.
A8 knockback from Brute Justice when they all combine.

You can also use Tempered Will to cheese Heavensfall in T9 and slams in Leviathan.
