Is that a gun????
It's a crossbow.
Or, for the gun-savvy in our audience: "It's a Dire Fiendish Smith & Wesson chambered for 3-inch wooden bolt rounds with metal alloy tips. An expert elven bowsmith has lightened the lever-pull and smoothed out its reloading action, and added night sights plus a competition-grade recoil compensator."
Interesting preview. The Pit Demon sounds like "What if we reduced the Cadaver Collector's damage output some and turned it into a commander?" -- It'll be interesting to see how that works out.
Marilith sounds like a fun beater. Maybe not so much on the engagement round, but on every round after that it should be a blast. Excellent defenses as well. I'm not a CE specialist, so I could be wrong... but this looks like an interesting alternative to the Hill Giant Barbarian in situations where you want to huddle down and hold a location (shared VAs, for example)?
Demonic Gnoll Priestess sounds like a tech-heavy figure. Interesting to see that, along with the upcoming Orc Wizard who also seems tech-heavy.
Bluespawn...looks like the paint master. Amusing.
As far as the Dwarf Sniper goes, this "explosive bolt" thing better be very impressive. Otherwise he'll be over 2x the cost of a Steelheart Archer, for virtually identical performance outside of higher defense.
