Incredibly low, as it should be though; I read on Uo Guide about 1/10,000 chance and read posts hear on stratics claiming 1/50,000 chance (range is a harsh mistress) I've burnt through roughly 1.2 million boards over the last month and gave up

I recieved a lot of oak kits, a 6 ash kits, 9 yew kits but unfortunatley no h-wood kit; I don't mind though, I wanted to do summin with the regualr boards that had been sitting in a container for so many years

I'm going to leave the h-wood quests be; The Em Storyline and ToT3 is far more fun than wiping blood away from my eyes hoping for a h-wood kit

My advice would me a spawner, use the time instead to farm powerscrolls, gold and replicas, sell them buy the kits, On a vendor in Luna on Europa there priced at 24 mill x (seems to have a few in stock piled on top of each ther too)
