im gonna use oak planks is there anyway to get them cheaper then 250ea?

There is a lunar spell to make planks, however I think it's more than 250 when you add the cost of the runes. I'm afraid not, sorry.

Lunar spells are good for this in some ways - you will save money and if you can craft nats - your sorted

 

 

 

Only annoying thing is you have to do them one at a time, still good though

 

 

 

 

 

Another good thing to get planks always oak is the Mini game ipetuous imps - Eclectic imps give 4 noted oak planks quite often.
