So far, it seems that the new advertising can be understood wrongly as reference to a "XP offline trainer", while in fact, the XP mentioned there is probably a reference to "skill experience". Currently, you cannot get offline experience in Tibia.
For me personally this is an example of misleading ad, since EVERY gamer out there will think that this is a reference to making experience for levels (XP is an universal short term that usually applies to the experience to be made for levels). Active Tibia veterans will probably understand this as well, but they might be shocked at first glace with this ad.
EDIT: Although people downvoted me, rest assured that people INDEED was confused by such thing appearing in Tibia.com website. They even changed the image text to avoid confusions and questions like mine coming from newcomers or people returning to the game!
So, you cannot get experience offline currently in Tibia. I rest my case.
