I agree on the Witch Hunter front, I'd almost argue this is the missing 'other' Henchman that the keyword has been missing for all these years. Resupply for those creep along's, or if Bura is feeling more selfish to ensure Remember the Mission or Overload get off (really nice for adding some OoA Interacts, besides the Queller, giving a little more versatility to the keyword).
Not sure how the 'ignore shielded/incorporeal' from Shielded Bullets will come in too much as I've yet to face much of either (though I imagine that'll change as I face different players and crews (I know ressers have a fair bit of incorporeal, but beyond that my knowledge is limited).
Crushing force is really nice for repositioning, either for setting up schemes, and Sanctioned Spellcasters (ensuring in range of any Soul Stone user for Fast) in that respect.
Healing trigger on the sword is nice, but Tomes will usually go elsewhere if you're cheating though being a henchman you *could* stone for it, though there likely will be better choices for stone usage, but nice to have in the toolbox.
Last, the Shielding handed out is nice especially if trying to keep a specific model alive just a little longer.
I imagine Cavalier and the Guard Keyword would likely appreciate Bura too, for the ignore incorporeal and shielded. Curious to see what the 'Bracer' minions look like, possibly like Guard patrol but with more defensive tech? Look forward to finding out either way
