Crystalis/Nadare's

Soon after entering the North side of Mt. Sabre, you'll come upon a large building. This is Nadare's Inn, and the interior of the Inn is a small but functional safe haven (once you reach it, you can Teleport to it in future). It has both beds and a shop if you need it.

General Kelbesque
After collecting the prison key and heading through the left cavern, you will encounter General Kelbesque outside.

Game Boy Color
Kelbesque's ranged attack is a ground stomp. It causes debris to move up and down the screen, before changing direction to the left or right. However, is main threat is simply from walking around the area to inflict significant damage. You must heal if below 40 HP, even if you do not hear the low hit point warning.

When he is defeated, you will get the flame bracelet. Open the door to the north and pass through to get the Paralysis spell and to reach Portoa.
