million B.C., and at certain locations in 600 A.D.

Money does not transfer into your next game in New Game+ mode. To keep your wealth, before
facing Lavos at the end of Black Omen, buy everything possible from the merchants until
your funds are exhausted. Visit the trader in the Prehistoric Era, and trade for as many
of his items as possible. Then, defeat Lavos to successfully complete the game. In New
Game + mode, your items will carry over. Sell all the unwanted items for money in New
Game+ mode.

Defeat Lavos at the end of Black Omen, and successfully complete the game to unlock New
Game+ mode and the Dimensional Vortex dungeon.

When on the Black Omen, you will encounter a Blubber Hulk (which at first looks like a
tornado on the ground). Approach it, and have Ayla use Charm to get a Strength Capsule.
Then, run away, and go back through the door you came through (with the two Nus), and
repeat as many times as desired.
