Okay, I decided to make a few edits after reading through it again and letting it sleep overnight.
1. Fixed a typo.
2. I changed Sword Mastery in the passive skill to Swordsmanship. I misread 剣術 as 剣技 which was used for the active skills.
3. I changed Sword Mastery and Fighting Mastery in the active skills to Sword Skill and Fighting Skill. I had a hard time interpreting 剣技 and 闘技, but after rereading the previous cancelled version of this, it is actually an active skill, so mastery wouldn't make any sense.
