Pursuant to the issues I discussed in an earlier post, I wanted to see how tough a "hard" or a "deadly" encounter was, and so I tossed the group into a very linear adventure with a clear "This is the hook!" focus and their choice of which type of dangerous path they wanted to take to get there.
Long story short, sirfox's warrior cleric Gimlet was formerly a member of a mercenary company tasked with keeping the peace in the largest nearby campaign city, and his pre-game background was that he left that group in disgust at corruption within it. I built on this background by saying that his former captain had been hanged for treason on the strength of Gimlet's testimony. But what Gimlet had not known at the time is that while dangling from the gallows, his former captain had been offered the opportunity to sell his soul to Orcus in exchange for revenge etc., etc., and had taken it. Thus, Gimlet's former boss returned as a vampire who is granted "seven years of continued existence" for each soul he sends to Orcus. Naturally wanting to front-load this a bit, said boss decides to start by murdering just about everyone he knew and turning them into undead minions. The party, happening to pass through the city on their way to another mission, happens into this situation when the boss spots Gimlet on the streets and sends his minions to attack.
The first act of the scenario, which I'd envisioned being something like a Call of Cthulhu-esque investigation tracking down the various people involved in the boss's trial, didn't really go as I'd hoped. I gave Sirfie a list of the various people involved in the trial, as Gimlet would have known who they were, but it was probably too big of an infodump  and the party just sorta vagued around the city a while until they finally latched on to one and waited for him to get attacked. Once the attack actually happened, tho, they did a good piece of detective work to track the boss's minions back to his lair.
The second and third acts are the assault on the vampire's lair, i.e., the former captain's house in the city and the catacombs underneath it. This is where the tactical focus/difficult combat aspect came into play. The ground level of the house had three different "encounter" areas of varying difficulty, but given their proximity, the nature of the encounters, and the villain's underlying ability to pretty much see everything going on at once and command his minions accordingly, it became one big furball, with the monsters coming in waves one or two turns apart. The six ghouls, probably would not have been a problem. Six ghouls plus two hellhounds, a bit more of a problem but a self-correcting one as the hellhounds' fire breath hits the ghouls as much as the party. Six ghouls, two hellhounds, and two helm horrors? Yeah, that's a bit much for five 4th-level characters.
Not quite a fifteen minute workday, but enough that the party wanted a long rest, and I couldn't blame them. Then down into the catacombs... where they fought six more ghouls and a ghast scrunched up in a tight corridor... then another six more ghouls and a ghast who were all praying around a statue of Orcus that enabled them to regenerate at the beginning of their turn.
Oh, ye gods. So. Grindy. -.- That was a seriously bad encounter design, Gneech. And of course, they wanted another long rest at the end of it, and it would have been foolish of them not to take it. Definitely a 15-minute workday that time.
So, yeah, lesson learned. I didn't care for it. I much prefer the freewheeling sandbox to the grindy, grindy railroad, and so I have refactored the rest of the scenario to be closer to 5E standard guidelines (although the vampire at the end will probably still be pretty tough 'cos, y'know, vampire boss fight). Once we are through with it, I'll be going back to the "smaller, lighter adventure hooks but more of them" mode we were in leading up to it.
On a related note, at AnthroCon sirfox let me know in rambliness inversely proportional to the amount of rum and cola involved ;) that he is all about the phat l00tz. If I understood him correctly, anyhow, he'd like to get some cool "signature gear" that does things beyond the numerical +x bonus, which I must admit is how I prefer magic items myself. Ironically, there have been some items like that floating around (such as the ones guarded by the spectator in the Lesser Spellforge), but the party has tended to turn around just as they got close to 'em.
Last session Gimlet yoinked a pair of magic hammers and shields from the defeated helm horrors, but unfortunately they were (by design) of the generic +x variety, merely being components of the helm horror manufacturing process. On the other hand, the party is in the big city, maybe they can find a purveyor of fine weaponry who would be willing to trade for something more interesting, once they've climbed back up out of the catacombs.
Sirfie also told me a while back that I had been described to him as a GM who was stingy with magic items, which I have to admit came as a surprise. My general goal has been to operate more-or-less within the parameters set by whatever game system I'm using, tending to randomly generate and then tweak-to-personalize loot when the players come upon it. However, having cut my teeth on 1E, I do also believe that treasure, particularly magic items, must be earned (or at the very least searched for). That means that choice items are often down side-passages, hidden in secret chambers, or being used by the baddies against the players first. For players used to CRPG- or MMO-style treasure "drops," this might seem stingy I suppose, but in those settings any given piece of treasure rarely matters anyhow compared to the item it's replacing. A +0.15 sword doesn't actually change anything regardless of how prettily it shines!
But the biggest factor has probably been that we tend to play low-level games, and low-level games tend to have low-level gear. I think the longest contiguous game I've run was Red Hand of Doom, which went from 3rd level to 9th level if I remember correctly, with a short-lived 10th - 12th sequel game. Certainly the players had some pretty nifty gear by the end of that (red dragonscale armor is a particular standout I recall). The characters in the Silver Coast game will almost certainly hit 5th level by the end of the next session (*sobs* TOO SOON!), so magic items will probably start showing up more often as their adventures scale up to match.
 NOTE TO MYSELF: Two clues is too few, and four clues is too many.
