The Lion's Rock is an area north-west of Darashia.
There is a series of riddles within the dungeon, the reward of which can yield the Noble Lion taming item.
Some creatures here are unblockable spawns, like the pharaohs or Demon Forge bosses. The strongest creature on the first level is the Bonebeast. There are only 4-5 of them. Ancient scarabs and Roaring Lions are only on lower levels. And they are the only creatures there. Be careful on lower levels, as Ancient Scarabs spawn fast and can paralyze and block you. Roaring Lions are easier to kill, because they do not poison or paralyze you, like the Ancient Scarabs does.
