Blightshadow Scorge, a new scout prestige AA, has an incredibly low hit rate. The issue is that it's a spell, rather than a combat art. This is a scout only AA, and scouts (other than bards) don't have spell skills (disruption for this one) as a base skill. Because it's not a base skill for the class, we can't even increase it through snacks or equipment. With 0 disruption, Blightshadow Scourge has about a 60-70% resist rate on orange con mobs, 50-60% resist rate on white to yellow con. It rarely hits, making it fairly useless, but this is one of the end line new AA's for scouts. Since it's a scout only AA, I assume the fact it was made a spell rather than a combat art is unintentional or a bug.
