Sorry, I got a massive load of homework. You can't buy elixers but if you are lucky enough to get a mammon (nemesis) and protect it because it might carry elixers (There are 2 types, and the other 1 carries ethers), have a thief on your team and equip the ability Rob Blind (thief lvl 11) Make sure your thief is faster than the mammon and brave 3 times to use steal 4 times.
