Talaturen has changed the system like real tibia so now you can't just say : HI , First Shaman Addon , Yes...
You need to look it up on tibia.wikia.com then you see what to say.
I bet you say like ( Hi , Task , Addon , Yes ) After that ( Hi , Addon , Yes)
Second Addon follows like this (Hi , Addon , Yes , Yes, Tribal Masks , Yes , Good Bye)
Hope this will help you out =)
