Level 1 (Light Campaign): Unreachable gold
There are two pots of gold to the right of the door which is opened by the lever, high up in a cove created by a crumbling wall. Quickly press the lever, then stand on the top of the door as it goes up. When the door is fully open, jump onto the ledges and up to the gold.

Stand in the shallow water surrounding the shining cross to heal your wounds.

Level 5 (Light Campaign): Safer route
Save the Halfling from the Orc. She will show you a safer route through the first part of the level.

At the point where four large rocks tumble down the narrow mountain path, stay on the right-hand side of the path to avoid being hit.

Level 7 (Light Campaign): Lighthouse treasure
Listen to the caged Goblin near the start of the level to learn about the treasure in the lighthouse. As you leave the boat, the lighthouse is the first big building you see. Carefully follow the ledge around the base of the lighthouse until you come to a door. Enter it to get to a room with treasure and the map of Naglagard.
