So at lvl 4 the PCs foiled the plans of a Shade. They watched her via a communication device dispatch an assassin and dark justicier to deal with them.
Level 5 and a tenday later they were traveling with Cornyr fairly safe right?
Near Arabel tge assassin struck. +10 on initiative, nightfall stealth role beat passive perception. Advantage on initiative, 28 assassin won.
CR8 vs 5th lvl PCs. RAW around a medium encounter. Last campaign involved lots of bhaalists. They usually used hold spells/command.
First strike. Critical hit. Base damage 1d8+4+6d6 poison. 3 attack. Next strike 20+ dropped the PC to 0. 3rd attack I targeted the downed PC putting them close to death.
Assassin then used shadow step (refluffed shadair kai as Shadovar ) and ran. End of encounter.
So that was it. Fiendish to a crit, raising tension and an assassin being intelligent and well an assassin I did a reasonable attempt of killing the PC's.
Some of the 5.5 reworks the monsters hit like trucks relative to 5.0. Goblin hexers, various cultists, assasssins, mages, archemages, performers all hurt. Hell Lost Library adventure has a mage apprentice that hurt lvl 1/2.
So several things going on.
1. DM special. Added a race to an NPC.
2. It did its thing scoring a crit.
3. Focus fire on one PC dropping them start of round 1.
4. Struck the PC once downed.
5. Shoot and scoot. Assassins mobility it got outta dodge.
PC chosen was random. Each player rolled a dice lowest got targeted (I do this when I suspect something will suck. Wife's at table she rolls the lowest she gets hit. No DM favorites).
Player was kinda shocked. Also the youngest player who has a very nasty striker type. They live action economy command or hold person has a 75% chance of success if combat continued.

Ok to make a point. I'd be really careful about this shoot and scoot stuff as an ongoing tactic. The players should be able to come up with some way to deal with this kind of attacks going forward. Not necessarily easily or cheaply. Otherwise your just putting them in a horror movie.
It's easy to turn lower level games into unfun games if you use stuff that the party can't deal with too often. Players have to feel like they have some ability to defend or mitigate attacks. Honestly you may find going forward that every decision will be much slower and much more tedious as they attempt to minimize the chance of this happening or even to decide if they should confront baddies. too much of this could slow your game to an indecisive crawl. I once derailed a campaign I'd been building for a year doing stuff like this. When the drow hit the party the last time because they were finally powerful enough to deal with them they just left the country and never looked back. In retrospect I was too good at showing them how awesomely bad the drow were. Cost me a lot of time. I had to put months of work in the folder and start over. I was a very sad DM.
