With today's server save, Tibia has adjusted the base stats of several monsters living in the gnome deep hub areas which were implemented with the last winter update.
Those monsters have now received higher armor and health values as well as stronger attack spells. Due to these changes their difficulty level, which is displayed in the Bestiary, switched to "hard".
Players who had already fully unlocked such entries will automatically receive the additional 25 charm points right away even if they do not yet have 2,500 kills of the respective monster. Those entries will remain fully unlocked.
We recommend players with lower levels to approach these monsters with caution. Especially Warzone IV, V and VI should now be more challenging and therefore offer a more balanced difficulty/profit ratio than before.
