I'm on my way to 45 herby (well only 44.... Greenman's Ale is such a good drink), and I'm doing is killing Chaos Druids in Edgeville to get enough herbs (using the Tip.it herby planner to see how much exp I could get with the herbs I have, then feed that into the herby calc to see what I need to get). After all, that I just bought lots of second ingredients and I'm currently mixing the potions (or would be until my computer decided to blow up - leaving me with a dead motherboard until I solder some new capacitors onto it.....)
