The Immortal/Weapons

Sword
You have this sword from the beginning of the game. It's pretty standard and is good for killing trolls and goblins.

Elven Sword of Agility
This sword can be found in the second level. It is similar to the standard sword, but swings somewhat faster.

Troll Bombs
You are given three of these in the third level. They temporarily paralize trolls, allowing you to evade battles.

Troll Ritual Knife
This item is found in level three. Throwing this on the ground announces a battle of the death between two nearby trolls. This will help you evade battles.
