This flog is tonking us everywhere lol <| sep |> T ' lan Imass are immortal , but not invulnerable . Being able to turn to dust is a huge advantage , and if they lose an arm , or a rib , or half their skull they can still carry on . As such , a group of Imass are considered a very deadly threat , especially as they have had 300 , 000 years to hone their skills . They can be rendered useless , as you have seen . My understanding is that those Imass are alive , but cannot movedo anything . HoC Spoilers There will be some more examples of what can happen to an Imass later on , particularly in HoC . There are specific examples of how to render an Imass useless or how to eradicate an Imass entirely . <| sep |> I always liked Lem Lemoncloak for his policy of hanging Frey ' s , ask questions later .
