This is out in PDF now, havent looked into it, but yeah check your emails and all that.
I glanced at my PDF copy a couple minutes ago. It looks like they fixed the table of contents, it's no longer a jumbled mess like it was in one of the previous updates. Now everything is neatly bookmarked and easy to find.
Upon getting the PDF, I first noticed their Advanced Weapon Masteries chapter. Initially I thought this chapter was going to be like the Weapon Masteries in the 2024 PHB, a list of properties found exclusively with certain weapons. It is and it's not. Each weapon comes with a Superior Strike such as Hail of Ammunition, Skewering, Reeling Blow, etc. But then the chapter gets into Advanced Techniques based off of a certain weapon property such as Light with its' Light Mastery
Light Mastery
At Tier 1, a person using a weapon with the Light property has two advanced techniques-Lightweight and Multiweapon Fighting. At Tier 2, they gain Superior Strike: Light. Tier 3, it's Combination Strike and Riposte. And lastly Tier 4 has Featherweight and Swift Striker. It looks you get them at 2nd, 6th, 10th and 14th level.
Other than the chapter on Advanced Weapon Masteries, I just checked out the Shinobi Wizard subclass and the Tatsumi species. No changes to either one. What do you guys think about this PDF's Advanced Weapon Masteries?
