I was just wondering about particular items that i essentially have part of and need another. I have a red amp, a blue amp and a yellow amp. Now the big question is where can i buy/find red yellow and blue barriers? Also another question i have is about the item "summit moon". I have the magic rock "moola". Now all i need is a fully grinded cane. Now what im trying to ask is should i grind a cane to +50 something or grind a club to +9? Since in the guide it said something like level 100 for the cane and level 140 for the club. Is there any difference between the summit moon made from a cane or a summit moon made from a club? Any suggestions on the best way to do these particular tasks? Thanks in advance.
