im not sure what started it but im a dragon monk and while i was killing metor spiders by trengal keep i got a message you train for reed of the wind , you need more training . So i kept going it took a while but i now have Reed of the Wind I.
I dont know if it was intentional or not but iI got it. There wasnt any kind of starter for it ether, just happened, Strange, No one else in my party got the skill or the message, it may be a bug I dont know. Just glad I have it for now.
