What do I need to do here?

Hint 1 of 29:

Save Andromeda, kill an awful monster (Kraken).  Not much really.

Hint 2 of 29:

Actually, you don't even need to solve this puzzle.

Hint 3 of 29:

You would miss out on the 50 points, though.

Hint 4 of 29:

One thing you could do is run through the rest of the game, figure
out what items you did not use that clearly must be used from something?

Hint 5 of 29:

I actually found the solution quite by accident.  Just playing around
with different things.

Hint 6 of 29:

The name of the Tarot card that got you here is a hint.
