If is only for roshamul the price of spangehelm is around 1/3 of coif so is better to use spangehelmet, the only diference spangehelmet. The only difference between the 2 in roshamul is you can imbui imbue the coif with magic lvl, i personaly lvl. I personally prefer to use distance in paladin helmets some pep people prefer to use magic lvl but dosent doesn't change much, if you dont got any i much. If you don't have either I would buy the spangehelm, if spangehelm. If you already have coif dont it isn't worth to buy buying it just to hunt rosha
