YARC Behind the Screen: Monsters & NPC’s

Everything I’ve posted about YARC has been player facing stuff. This is where the whole tone of any game really happens in my opinion. It’s the options that are available for the player character that make things move. And that part is basically done. The players have a draft of the rules and it will be time to start rolling some dice in the near future. But now I want to start looking behind the screen and stuff to make the life of the DM easier.

One of the most useful axioms is that monsters and NPC’s don’t have to follow the same rules as player characters. Sure a DM can use that to cheat and just outright kill or outshine the PC’s but the true intent is to make the DM’s job easier. The less time that the DM has flip through rule books or try to puzzle out a page long monster stat block is time away from actually keeping the excitement up. This where so many of the old school games shine. Easy and to the point monster stat blocks.

If you remember from the early posts, another goal of YARC to make it so that the DM could grab just any old school adventure and quickly and easily convert it while running it.

If we boil monsters down to their most basic, there’s three things that become the core mechanics of monster: HD, AC, and Damage. Hit Dice are basically a monster’s level. It’s how many Hit Points they have plus how powerful they are overall. Sure you could roll for HP but I’m running a standard of 5 HP/HD. As far as Attack and Save Bonuses. That’s the HD. Armor Class can be just from what’s listed or compare it to what the AC might be for a player character and if you’re using a source that only has Descending AC the just take 19-AC to get the Ascending AC. Damage same thing. Just use it or think of it in terms of the what’s available to the player characters. Then adjust or run any special abilities as needed. No this isn’t a scientific approach. It’s a lot of instinct and what feels right. So let’s make a freaky swamp monster

It’s pretty tough for single low characters but it’s going to go against a whole party. Let’s give it HD : 3. So it’s got 15 HP and +3 to Attack and make any checks and Saves.

It’s got a tough rubbery hide. Let’s say that’s about leather armor so AC: 12.

Its got long nasty claws. Those are sort of like daggers but it’s really strong so let’s make damage: 1d6.

It’s a Freaky Swamp Monster so it needs a couple of freaky powers. It lives in a swamp so it should be aquatic. I know let’s make it a stealthy predator so give it Advantage on Stealth type checks in a swamp. And last let’s give it a Swamp Gas power. It’s a fog that blinds and disorients everybody but it.

Now, I know that for higher HD monsters the HD as bonus thing breaks. So I’m running with a max bonus of +10. So a HD 18 Demon Lord would have only a +10 and 90 HP. It’s a good max while it does make the monster powerful without being overpowered plus anything with that many HD is going to have really nasty special abilities that really won’t depend on hitting high level characters in combat.

And those special abilities are where a lot of monsters shine. Don’t even thing putting those into a paragraph or a sentence for use at the game table.

  • Just
  • Use
  • Bullets

IMHO, too many monster books are just too damn wordy.

I call them Death & Taxes

Let’s talk about NPC’s a bit. Unnamed, and unimportant NPC’s basically use a monster stat block. That city guard, random pickpocket, tavern keep, or merchant. They are all going to be 1 to 2 HD and might not ever be seen again or you might need even any combat stats for them. And that’s an important note right there. If an NPC isn’t going to get into combat then you don’t need stats for them.

Here’s a confession. Vasha of the Night Market is an NPC that I’ve used in two campaigns. At the very least, the player character know up front that she’s a powerful magic-user. With even the smallest bit of research, they learn that the city elders let her do pretty much whatever she wants. She’s the only person that the head of local Thieves Guild actually fears. It’s clear to the players that if they do something stupid then eight kinds of hell is going to come raining down on them. I’ve never made any kind of stat block for her.

But if that NPC is the big bad. Oh hell yes. Go crazy and make that cool stat block. And make one’s for NPC that are reoccurring that you just need to have them go into combat either with or against the player characters.

Then there’s that special time that you want make an NPC with a whole sheet just like a player character. Always keep one of those in reserve.In case a player doesn’t show up or even if there happens to an extra player show up.

I know this has been a rambling post. So it’s time for me to shut up. I’ve got a game to prep for this weekend.

And here’s the Freaky Swamp Monster

HD: 3 (15 HP)

AC: 12

  • Aquatic
  • Advantage on Stealth
  • Swamp Gas: Blocks vision further than 10 feet. Save Vs Magic or Confused.
