I am using an LG G4, Andriod version 6.0.
I am currently using Lem, Val, Kyra, Sajan (in that order)
Lem was at Shrine to lamashtu with Sajan, and encountered the Hook mountain hag
On the card it says "Before you act, succeed at Arcane or divine to use attack spells"
However, it's never given me the opportunity to make the check, and just has me fail.
(I've also seen this with the goblin warchanter)
