Follow your pawn and jump past the fire. Defeat the goblins and enter the cavern. Jump down the ledge and touch the firstone to summon more pawns.
Follow the path until you encounter more goblins. Defeat them and look around for healing items*. Destroy jars and crates to obtain these items. Follow the path upstairs and clear the holding area to save Ser Ashrore. Talk to him to obtain a panacea.
Continue following the path and exit to the antechamber to find a harpy. Defeat it. There are crates and other items at the end of the walkways. Open the chest then join the survivors. Follow the corridor and open the chest on the way. Keep on following the path until you reach the Grand Hall. Head to the large door to trigger a boss battle.
You are now against the Chimera. It has three heads with a life bar each. The tail inflicts poison and the goat head casts spells. Guard with your shield then counterattack when possible. Take out the snake tail first to prevent poison attacks and use jump attacks to interrupt the goat head's spells. You can also grab hold of the snake tail and attack it while clinging on it. When it's attention is focused on your allies, you may attack it from the side or the rear. Continue until it is defeated.
