How much does it cost to level Alch?
 

Looking at the ingredients it looks like it's going to cost a pretty penny. I wanna get up to making ant potions, but not sure how much cash I need to get there. Anyone know?

20,25k to level to... what's that number - 162? If you want some advice, stop once you can make sow & shrink pots. Or don't start at all and just buy whatever you need - the profit margins are very small.

20-30k+ to get 156 with 255 wisdom.
another 10-15k to cap at 170.

And yes the profit margins are rather slim for alchemy on p99. Probably due to the non-classic surplus of shaman on p99.
