Thanks for participating, just found it:
Sincerely it looks really easy, most of Tibians have been there (including me, a lot of years ago in Tibia real's), but somehow in Shadowcores you're not able to use pick at some places so I cba to get there, but there might be another way to get inside there, can't be bother to get there tho.
