The Plain People of Gaming: 13th Age monster-tech in GUMSHOE

Mutant_City_Blues_Cover01Continuing Ken’s theme of looting 13th Age for GUMSHOE twists, let’s talk about monsters. In 13th Age, monsters have a sort of rudimentary AI – instead of the GM deciding to use their special abilities in advance, they’re triggered by the result of the attack roll. So, for example, if a ghoul gets a natural even hit, it gets to make its target vulnerable. If a frost giant rolls a 16 or higher when attacking, it also gets to freeze its foe.

For example, here’s a basic human thug:

13th Age Human Thug 

1st Level troop [Humanoid]

Initiative: +3

Heavy Mace +5 vs AC – 4 damage

Natural even hit or miss: The thug deals +6 damage with its next attack this battle. (GM, be sure to let the PCs know this is coming; it’s not a secret.)

AC17

PD14    HP 27

MD12

Automating monsters like that makes the GM’s life easier. Instead of having to make decisions before rolling the dice, the GM can just attack and let the triggered abilities make the fight more interesting and complex. The thugs, for example, encourage the player characters to focus their fire or dodge away from the ones who have extra damage lined up for next round. Some of the work of making the monster cool gets shifted from the actual play part of the game to pre-game preparation, leaving the GM free to concentrate on evocative descriptions. tactics and other immediate concerns. (Triggered powers can also surprise the GM, which is always fun.)

GUMSHOE monsters and foes have a limited number of points to spend on their attacks, possibly mediated by an attack pattern. While the attack pattern does take some of the heavy lifting away, the GM still has to make decisions about when to spend the bad guy’s ability pools. Let’s try taking away as much resource management as possible from the GM. For general abilities, for every 4 points a creature has in its pool, give it a +1 bonus, to a maximum of +3, and modelling special abilities as special-case rules or powers triggered by a dice roll instead of the GM having to make a choice. Health, obviously, is unchanged.

Obviously, GUMSHOE’s smaller range of random results means that you’ll have to be a little more restrained when it comes to special powers – there’s a big difference between a power that triggers on a natural 20 in 13th Age and a natural 6 in GUMSHOE. Possible triggers for powers include:

  • Natural even or odd rolls – good for alternate attacks or special effects
  • Natural 1s or 6s
  • 5s & 6s – generically ‘good rolls’, useful for foes that have a chance of doing extra damage or inflicting some special condition, like stunning or knocking prone
  • Health reaches a certain threshold – perfect for countdown mechanics, where the fie gets nastier towards the end of the fight
  • The attacking player character has no points left in a pool – if you’re out of Shooting, the alien monster breaks from cover and rushes towards yo

You can also have a power be limited to a certain number of uses – a ghoul in Night’s Black Agents might get an extra attack on the first three times it rolls a natural 6, but no more.

All these rules are just for monsters and NPCs – player characters still get to juggle points and manage their resources as per the standard GUMSHOE rules.

Natural 6: The klorn’s target is impaled on its spear-teeth; +4 bonus damage

Frenzy: When the klorn’s reduced to 10 or less Health, it immediately makes a free Scuffling attack on the nearest foe.

    Agreed, this is a very interesting idea, and may well adapt this for the game I’m currently running.
