Casting spells across ethereal plane

[Willtell]

Could you cast a spell, cause blindness on a target on the ethereal plane if you can see them using the spell see invisibiltiy?. Where is information on this?.

No, only force and gaze effects affect ethereal creatures. It's all in the DMG, under special abilities; etherealness.

only force and gaze spell?????

Does that mean that searing light (Cleric spell) has no effect against Spectre?

 

[Macbrea]

Only spells with [Force] indicator after the school, Gaze attacks and All Abjuration spells work across the boundries. So, Blind/Deftness (Tranmutation) would not work accross the boundry.

And Searing light (Evocation) wouldn't either.

Spectres are incorporeal not ethereal.
But there would still be a 50% miss chance from a spell with a corporeal source.
