Magician/Lake

Island village
Use the pouch pouch of coins to get a lift from the ferryman.

Two enemy warriors are in the village. They have the same attacks and weaknesses of the first warrior boss. A third warrior is a friend who will gift you the usual 500 Gold Coins.

Enter all the buildings, restock on food and water, purchase everything, and listen to everybody in the guild house.

Crossing the lake
The Jump spell at level 3 is good for most jumps. The level 4 costs almost double mana, but it is necessary for high-jumps and long-jumps.

BOSS: drake
Its attacks use fire and poison, therefore you should cast some Ven Shield and some Fire Shield.

If you are low on mana, you can fight it using the Staff of Power (provided you found its two parts in the previous levels). The monster is weak against lightning.

You get 250 mana for clearing this level.
