OK, IIRC I was missing 5 skill points. The only action in your list I didn't do this last time was buying the fake Grail from Ismail
, and it gives exactly 5 skill points. I had discovered this before, but I didn't do it this time, as it was not in the list I was following.
I suggest you check it, and add a special note about this action, that it's not mentioned in the hint book.
And I was not aware it awarded skill points. Actually I find it surprising as it is something trying to fool you (earlier, you have a penalty if you get fooled and pay Yasser) so you should be subtracted points instead of rewarded
All in all, a very strange case
Are you aware of any other Sierra hint books that don't display the points correctly?
PS1. A feature I didn't know before, and I find it very strange/silly is that you must pay the gods both 1 silver AND 1 gold coin. I thought that a silver gives fiewer points, and you should give gold instead
of a silver to have full score
PS2. I was too lazy to find the exact action that gives you the one + wisdom point.
