Viziertim, check it again. The scarab's are not loosing max health after one dies (at the end of their round) There were 3 scarabs with 3 health. I kill 2 then he summons one more. Without him using devour he ends the round with 4 health. Thats another +1 when it should have reduced to 2 health since that would be max health = N. This is very repeatable. If you have 2 scarabs and you kill one at the end of there round if there is only 1 scarab they should loose 1 health and become 1. This also does not happen. Its the reduction to max that is not allowing for the correction due to bad code. The code obviously allows for the +1 perm effect of devour but does not keep a separate table for the factor N. Thus factor N gets a +1 perm boost at round end if a new scarab was summoned. Note that this only applies to NEW scarab summons. Thus the equation becomes N=(N +1 for newly summoned scarabs)
I wish they would fix some of the card effects... IE Scarabs. N does NOT = the number of scarabs controlled at the end of the turn. They get +1 for every scarab played and it never reduces.
