Night Lord and Mechanic Skill Builds

Assassin:
1 FJ > 1 Shuriken Burst > 5 Mastery > 6 Booster > Max Critical Throw > Max Physical Training > Max Mastery > Max Flash Jump > Max Shuriken Burst > Max Booster > 11 Gust Charm

Maybe get FJ before Mastery if it turns out L7 is better than a weak Shuriken Burst

I'd never recommend physical training maxed so early, depending on ur funding only put as many points as you need for dex. I would prioritize mastery/fj depending if you need more mobility or more stable dmg to 1hit/2hit ko more often
