Long story short; whenever I use Savagery, Supreme Harmony and Hone together, it immediately crashes the game. The crash rate is 6 for 6, even in different zones. Since my stability is pretty awful anyway, I don’t know if this is an actual bug or I just need to go back to leveling fist by turning in the missions and just avoid it for now.
I’m not really familiar with Blade so I don’t know what 4th/5th passives to use but as a datapoint I seem to be able to cast them (I went left to right, savagery hone supreme blade). I have a Blade fo the Seventh Son and Bladed Gauntlets. I also tried with Spirit Blade charged (replacing fist power move)
