One of the mechanics I love about Cortex Plus games is the way in which the way complications rise and fall with the narrative. With the right rolls your d6 mildly irritating can step up to d12 mortal enemy and back down again over the course of an adventure or sometimes even a scene. The same is true of physical complications, a flesh wound could be aggravated all the way to bleeding out without the need to introduce additional complications. Coupled to this is the dice pool mechanic, if an advantage or complication is relevant to your roll you can always add it to your dice pool before rolling.
Demon Hunters incorporates elements of Cortex Plus but, at its core, is a Fate derivative. Because of this aspects, while always true, have a single value (d6) and require either a free invocation or a faith point to incorporate into a roll.
The below draft rules modification shifts the mechanics slightly more towards Cortex Plus by allowing for the creation of aspects with die values greater than d6.
Aspects that are narrative associated can be stacked together, creating a single combined aspect. Physically link the individual aspects together by drawing a line between them or stacking them atop one another. When invoking stacked aspects choose from the following
1. Invoke each aspect separately as per the standard rules at the cost of one faith point per aspect. Each aspect invoked adds 1d6 to your dice pool.
2. Invoke the entire stacked aspect for the cost of one faith point. For each individual aspect after the first increase the size of your bonus die by one step.
For example during a scene the following scene aspects may be in play
1. Stampede of people
2. Raging fire
3. Choking smoke
4. Demonic hieroglyphs
The first three of these are narratively linked to one another, the fire that was accidentally started (because no Demon Hunter would ever start it on purpose) has built to an all encompassing maelstrom. These aspects can, if desired, be linked to one another. The fourth aspect stands alone and cannot be linked with the others.
Doyl, our demon Hunter, is trying to escape from the cultists chasing him but he’s not particularly sneaky or athletic so it’s going to be difficult. With plenty of faith points he could invoke the first three aspects to add a mighty 3d6 bonus to his roll. Unfortunately he’s only got one faith point, having relied on them rather heavily earlier in the scene. He invokes the stacked aspect to gain a bonus d10, hopefully enough to make his escape.
At this point astute readers will be noting that the standard 3d6 bonus will average a higher roll than the d10, so why bother with the stacked aspect? The answer is simple – cost, a single faith point rather than three while still making use of a wider range of the aspects in play.
During the playtesting I’ve done with this rules modification I’ve also noticed a secondary bonus – it encourages greater player engagement with scene aspects. Knowing they can get a larger bonus for the same cost drives both the creation of aspects and their creative use. It is also intuitively balanced, there’s nothing to stop the DM from creating or invoking stacked aspects using demon dice.
As always I’d be interested in anybodies thoughts or comments on this.
