So yeah, something else came across my attention while looking over the cards. Neither the Hail of Stones, nor the Wall of Pikes's attack include the Unavoidable trait. Going by the rulebook both should be unavoidable (as zone attacks and passage attacks have this trait) and I wouldn't even think twice about it except that all other cards have redundant wording. That is to say, they specifically call out that traits that they are understood to have. All other zone attacks, for example, have the Unavoidable trait (and there doesn't seem to be an issue of room on the attack bar of Hail of Stones) and the Wall of Fire, and Wall of Thorns specifically got errata to specify that their attacks are unavoidable. This leads me to wonder if there is something up with Hail of Stones and Wall of Pikes or if they are to be treated as per the rulebook and have the Unavoidable trait as well?
