Question re Ian Cathlan's armor questsFollow

I cant help you to much but can give a little info. Its well worth doing it. First part is in Antonica. Second Antonica and Blackburrow. 3rd is in Stormhold you have to kill defiled knights, crusaders, and caveliers. 4th is in The Crypt of Betrayal, You have to kill shrillers, beatles, and restless dead. 5th is in Thundering steppes, have to kill corpse feeders, sabertooth looters, unearthed settlers, and get bonechipper which is in the river bed drops of the skellies there. 6th in Thundering Steppes again, Have to kill Ott something named giant, steelhoof hunters, and teh skeleton troopers. Hope thats the info you wanted. And this is info on teh medium armor needed for ranger thats the quests i got.
