CHANGE LOG [V1.0]
1. Increase drop rate of monster unique materials (not-bone materials) in low levels guiding land regions (37% -> 63%, Bone rate 63% -> 37%)
2. Increase the number of all monsters unique materials to 3.
3. Increase the rate of great spiritvein gem drop 6 times (18% with the mod) without changing the unique materials drop rate)

Editor's note:
This mod's purpose is for people to save time grinding all those materials for augmentation and weapons customizing. You can drop that one level of geology in your build whenever you going to the grinding land and still got a lot of materials. If you decide to keep, yours collection will be 6 times more. 

I am open for feedback and changes so just drop your request politely in the posts section and I will consider make optional version or update this version.
