For those saying how tough this is.. I am at 99 tonics. I bought most of the sand and 8ish stacks of blood b4 the chest change as a hedge against a jump in price. Only thing I will continue to buy is the sand. I am not super rich. It can be done if you want to do it..., This was a. Great addition to GW2. If you want a cheap mini grind, do the otter enrichment....
