TLDR: I would like to propose that Umbrite be moved from 300 to 200 tomes.
Currently, Umbrite is used for the 240 stage of the relic. You use 1 lump of Umbrite and one unit of crystal sands. The Umbrite can only be obtained with tomes and the sands can be obtained via many ways which do not bottleneck the process. You need a total of 240 processed units. One sand and one Umbrite provide 3 units. 80 Umbrites will be required total. One day's worth of roulette gets me 2 Umbrite. A hardcore grind would last a minimum of 40 days which is comparable to the 7 weekly a12 gears for the 260 shire weapon. It is possible to get more tomes but past this point it is no longer a game.
It made sense for the 240 weapon to take 1-2 month worth of work when it was the top weapon to get but now it's a bump in the road. From what I understand the next stages do not take nearly as long. I do not see a rational reason for this lesser level weapon to be required to last longer when it is possible to just loosen the bottleneck. Right now Umbrite costs 300 tomes. If the price was moved to 200, the process would last an estimated 27 days from 40 as a daily worth of roulette gets me about 600. I feel this is a much more reasonable amount of effort for a weapon people would most likely not use at all.
