I think there should maybe be a better way of getting clay, I know you can buy it in the shop but if you need alot of it it can get expensive real quick. also the hardened clayblocks are kind of expensive if you want to build alot with it. so maybe it would be an idea to get claygen as a plugin this makes you create clay by putting water ontop of gravel and over time it changes. it can also be made that you need to surround the gravel in something before it can change (this is up to the owner/head admin). I really hope someone agrees with me and maybe this will get added.
As said many many times, there is a big update and bugfix coming up which will improve many of skyblock's problems. Please be patient until that time. -SS
