Not sure how GFs are sending groups of us flying from extremely long distances. must be latency issues on the servers. I was pretty sure it was pommel strike that sent you prone. Eh. I've had the same "missing" problem with Lashing Blade too. That answers my question about Flourish. Thank you.
From what I saw the first death was to Impact shot, for sure, just based off of the ~10k damage and push. The reason you might not have seen him is due to positioning. He may have been behind, or even possibly above (although that does seem like a reach on the pillar, i've had that and shadowstrike hit much futher than it…
From what I have seen, heard, and reported, disciple of strength is currently bugged and giving no bonus to power, etc. I still have it slotted for when it eventually becomes fixed, but Endless Assault works fine and it's always nice to have an extra 6% damage on that lashing blade or impact shot.
It did for me. At least I'm pretty sure it did, but I found I did more dps using sly flourish anyways, so I couldn't give you a 100% answer. The best way to test it is to go to the PVP building and hit the dummies in stealth and see if the buff pops up under your portrait.
Batiri, wild dwarves, lizardfolk, pterafolk, and yuan-ti. Less common: aarakocras, chuuls, hydras, nagas, troglodytes, trolls, and wyverns. And of course, dinosaurs.
