I suppose the question can be interpretted in three ways
Q1. Are there items which can improve my arcana level (say, from initiate to apprentice) while I use them?
Answer: Yes, but these are particularly rare. And very difficult to come by.
Q2. Are there items which can improve my ability in arcana while keeping me within the same arcana "level"?
Answer: Yes, there are. These are mostly items such as wands; which tend to be used by lower level mages and are easy to get a hold of, and at higher levels staffs; which the mage must make themself. I've never seen a mage's staff take the form of a chained weapon... but perhaps it's possible
Q3. Are there items which can shortterm boost my abilities in arcana?
Answer: Use the arcane "drug" mageburn. But it's addictive, and weakens arcane abilities in the longrun.
As to the use of the specialised chain weapons... I don't see why not
