The Immortal/Weapons

Sword
You have this sword from the beginning of the game and use it throughout Level 1. It's pretty standard and is good for killing goblins (and perhaps Trolls).

Elven Sword of Agility
The sword Solondul of the Elven Lord Arinar. It can be found in Level 2 with Arinar's bones. It swings somewhat faster, compared to your standard Sword.

Troll Bombs
These Bombs are kept in a chest guarded by a Goblin in Level 3; you must pass by him to take the 3 of them. They temporarily paralize trolls, allowing you to evade battles.

Troll Ritual Knife
This item is found in Level 3 after killing a Troll. Throwing this on the ground announces a battle to the death. This will help you evade one battle with two nearby Trolls when you reach the Troll territory later in that level.
