This question has been asked before,and though I believe some one else suggested other possibilities to get the items you are looking for, and assuming things haven't changed by updates in the simpler basics of how the game works,there is a simple answer to your situation.

All the things you have lots of are more easily found than the special ones you seek, which are invaders materials and its these that are needed for the more advanced hero /shaman equipment. 

If you buy or win coffers , you almost, if not exclusively, will only get basic materials, so you are wasting your time looking for invader materials there.

If you want to get invader material you are just going to have to kill more invaders, and even then it is a slow process, because it's designed such that they drop less of these, for what are obvious reasons.

Though you can get these materials from lairs ,do not expect that this is the answer to all your prayers as you may not get anything from them, and if you do, it might be low quality.

Additionally.

If you want Centurion or Barbarian material you can get these from the clan store.

 Though I took the trouble to answer, I had my suspicions abbout this opening post from the very beginning.

It was too familiar to me, but I wasnt going to waste time trying to find the source of it by searching the forum.

It also struck me as odd that the registration date was non existant, (now showing as yesterday) so the whole thing didn't feel right.

Now the O.P.  has been edited and a link has been added , which I can now suspect is either dangerous or spam

Edited below.

Often searching for old posts can be tedious, but I  just used forum search for something similar, and found one ,by Executioner,and fairly quicky, with it being identical, and top of the list. 

 I was having trouble opening it ,but here is the link.
