Hobbit, The

At the end of each level, you will be taken to the vendor. Here, you can buy upgrades for your rock bag and medicine chest. Each affects your carrying capacity. The upgrades are as follows:

Medicine Chest
First upgrade: +5 antidote and health potion carrying capacity; total of 10 each.
Second upgrade: +5 antidote and health potion carrying capacity; total of 15 each.

Rock Bag
First upgrade: +10 rock carrying capacity; total of 20 rocks.
Second upgrade: +10 rock carrying capacity; total of 30 rocks.

Stay behind the debris until all of the fire is gone. Even though he stops, some fire is still there and it will kill even if you take one step out. The ring will not help you at all.

On the last level when you meet Liana, she will start fighting the Goblins. There will be an unlimited amount of them.
If you need to level up, stay there for awhile and collect all of the courage points.

When fighting the spiders, stay up on one of the rocks. Throw rocks at her minions. If you run out of rocks, just slpp on your ring and sneak (or she will hear you and attack), over to some rocks and get them.

There are three items you can acquire throughout the game: the walking stick, throwing rocks, and Sting. The walking stick can be found in a chest in Bag End at the Shire (first level). The rocks can be found in a grove of apple trees in the Shire. Sting is obtained in the troll cave at the end of that level.
