I was wondering if there were any restrictions on Iridium Warden's second mentioned ability of attacking a creature after blocking them, if it has attack points. For some reason when I use basilisk blood on Iridium Warden, wait 6 turns, and then give rage potion, some creatures which should be killed are only blocked and not killed, such as Maxwell's Demon and creatures that have been given the Destroy ability. All other creatures, except for those i've noticed, will be killed by the Iridium Warden if lower than 6 HP. Are some creatures just immune to being killed by this roundabout ability?
