This tree is for one handed battle style. The trophy will unlock when you get 1 point in each "gift" option. You do not need to max out each gift to level 3, just level 1 of each will do it. The final gift will unlock at rank 16, so you can get it when you reach rank 16 if you have worked through all the gifts.
It takes 20 points to unlock this.
If this is not your main tree, I would recommend getting what you want out of your main tree and then saving 20 points up. Once you have 20 points, in the main area of the game where you have nothing to lose by dashboarding the game, spend 1 point in each gift for this tree, get the trophy and then dashboard close the game and it will not save the points spend. Do not quit to menu, or it will save
Repeat the above for the other trees you are not using and then you can keep those 20 points for what you actually want to spend them on.
