I finished the quest. The easiest (yet most expensive) way to them is to do 3-4 with 4CV and 2BB (which would get you 1-2 of DecoMat per run, if equipped w/ 4 searchlight).

The cheapest way to get them is by using 5SS + 1CL/CA in 1-3. You can get a DecoMat every time you hit the boss. This might be frustrating though because RNG compass may not bring you to the Boss node.

Don't farm on the same map again and again. If you get 4 at one map, switch to others. I limit myself on getting 8 per day so I finished the quest within 4 days.

The decoration is lame IMO.
