Magic is often used in published adventures for various purposes but it seems WotC rarely provides much info regarding the spells used to conjure the effect beyond "it's magic!" 
For example - the chains binding Hekaton are described as magically enhanced such that they are keeping Hekaton unconscious (and they are immune to most kinds of damage). There is no description of what school of magic this spell is derived from (making Detect Magic give an "it's magic" result), and no description as to what level it was cast (making "Dispel Magic" somewhat random based on DM fiat).
How do you adjudicate tackling this kind of magic when running these adventures?
