Onatree

From Arindal Wiki

All around the town center one may find hollow trees, in and under which the Onas feel homely. Still, if someone talks of the Onatree he almost always means the one 1E, which is by far the biggest.

The Onatree is pretty popular amongst young adventurers and experienced players who need to get rid of their Malus. The Onatree 1E has several levels, each of which houses ever more dangerous Onas.
