List ability that blocked by spell shield

[Asuna Tichondrius]

Is there the list that targeted spell that blocked by spell shield? I cannot found it anywhere.

From my testing it only procs for unit targeted spells from enemy units as testing with slow that affects allies didnt proc it. But there seems to be set of unit targeted spells that bypass it by default, heres the ones i found
1. Finger of Death/Pain
2. Shockwave/Carrion/BreathofFire even when unit targeted
3. Ensnare/Web
4. Devour
5. Impale if point targeted not unit
6. Channel if universal spell option enabled
7. Every Attack modifier (searing arrows) even when directly casted upon unit
