I am having trouble thinking of a good block gradation to use in my parkour multi-course that is on SMP 3. I plan on doing 4 difficulty levels: Too Easy (like dirt) - it should have very lame and non-valuable blocks that look terrible (poor quality), Mediocrity (like iron) - it should have some value but be cheap and easily obtained and somewhat good looking block (okay quality), Pretty Dang Hard (like gold/emerald) - it should have more valuable blocks that start looking cool (good quality), Diamond (like diamonds) - it should be the most valuable and cool looking (EPIC quality). It would help if your suggestions followed that format (Track name - list of blocks in order of first to last I should put down). Take note that the more expensive it is the longer that course will take to make. Thank you guys for your help!
