Probably intended. Sharra’s ability ignores the hit completely, deathtouch etc doesn’t work. So she probably “absorbs” the slam. I’m not sure how it works with protection.
Then, Slam should be “When […] attacks and deal damage …”
Because the way it’s written, I’m unsure if Slam damage should apply (it says “attack”, but there is the “also damages”, which could hint that damage has to be done.
Anyway, it’s definitely unclear on this point I think.
Well, I belive that the “damages adjacent creatures” doesn’t mean that the creature damage is dealt to the minios, but something like “The damage taken by the first creature is replicated to the adjecent ones” So, considering sharra takes no damage… the damage “replicated” is zero
Well, at least for me looks quite fine the way is working… if something takes no damage for whatever reason, make some sense none damage being spreaded either, seems more balanced IMO
