After doing a little searching online(using this website as a guide), I built a Greatsword for a player who wanted to have it as a weapon he only uses while Raging.
Base Weapon: +1 Large Greatsword
Level/HP/Save/Attack/Ability
5th/2/-/-/Weapon Enhancement(+2 Greatsword total) Least
6th/1/-/-/Quick Draw(weapon only) Least
7th/-/1/-/Weapon Enhancement(+3 Greatsword total) Least
8th/2/-/-/
9th/2/-/-/Furious(+2 enhancement while raging) Lesser
10th/-/1/-/Weapon Enhancement (+4 Greatsword total) Lesser
11th/1/-/-/
12th/2/-/-/Weapon Enhancement (+6 Greatsword total) Greater
13th/-/-/1/
14th/1/-/-/
15th/2/-/-/Ability Score Enhancement(+6 Strength) Greater
16th/-/1/-/
17th/2/-/-/Critical Boost, Greater(Critical Damage x3 instead of x2) Greater
18th/1/-/-/
19th/-/-/1/
20th/2/-/-/Speedy (+1 Attack at Maximum bonus) Greater
I wanted to be sure I built it right stat-wise before I really look into his "trials". After reading into Vansaya, and having one of my PCs mention a weapon from his past taken by someone who also killed his family, it was too good an opportunity to pass up.
