@mayo : Nah, clearly she's not lying since Gran Maria haven't said anything, and had things prepared.
Since he only need to pass 3 out of 5.
Economic - Gran Maria already prepared the ore she knew is enough to qualify.
Rock game - He's played this game with the angels before.
Combat - She was trying hard not to laugh at knowing Tia is his wife.
Negotiation - obviously Doram is a constant visitor to the village, so that's another easy pass.
So yeah, he already had the 3 minimum to pass in the bag already.
