I usually do this by complimenting her breast, and being nice and comforting her when she panics.
It depends on what you prioritize.
If you want to save Rose you need observation, hearing and speed (all 4/4); if you want to defeat the giant in disguise you need 4/4 reflex and 2/4 combat technique (maybe? ); if you want to reunite Rose with the deer family, find the architect's note and it's puzzle piece, or understand goblins or read Eiden's message across the sky (albeit you need observation) then choose ancient languages. What you want to do depends on you, but you max out, about 4 stats. I found toughness and strength least useful, probably because my strategy was to dodge at all cost, but if you want to attack them head on you should probably use strength and toughness (when fighting golems)
But @Nemeean_lion might be more capable.
Loved the the second book's 1st chapter by the way.
