(bug?) Warlock attacks never miss

Playing on my Droid Icredible. I've noticed that the warlocks are able to fire their flaming skulls through walls. Additionally, they absolutely never miss. Even if the skull dissapears 5+ character lengths before the corner I just retreated around it ALWAYS hits me for damage. Although their projectiles are magical I find it a bit ridiculous that I can be up to 3/4 screen distance away from it and still take the full amount of damage that I would getting hit point blank
