SuturedDefenseValue/NoPool

The rule on defense value read very much like the DV system started with a strong mathematical rationale (i.e. static defense based on the average number of successes from a defense pool) but, as Second Edition was developed, later revisions of the rules forgot this rationale and choices were made based on some other criteria that was never explained. Thus, some of the rules mention pools and some do not. Much of the confusion in DissectingDefenseValue stems around trying to match these pool-based rules with the others. This variation eliminates this confusion by saying "screw the mathematical underpinnings", and goes with the assumption that the intent of Second Edition was actually to completely eliminate references to pools for defense, but that they didn't quite get them all.

Calculation Order

This variant ignores any tie between successes and DV and treats any mention of pools related to defense as mistakes. No longer based on dice pools, this variant completely ignores the Order of Modifiers chart that is mentioned so often in DissectingDefenseValue. Instead, it uses the following order:

Step A: Determine your base DV

This step uses the same basic equations to calculate DV, but these are just considered equations, not dice pools per se. This step includes specialties and what would, in the land of dice pools, be called "internal modifiers" such as Hearthstone Bracers (ex2e.381) and weapon Defense. Unless usingSuturedDefenseValue/PenaltyConsistency, this would not include wounds or mobility.

Do not round at this point.

Step B: Apply Non-Magical, Non-Environmental DV modifiers

Apply any DV bonuses or penalties that come neither from magic nor environment. This would include wounds and mobility (if not usingSuturedDefenseValue/PenaltyConsistency), onslaught, stunts, virtue channeling, penalties from previous actions, equipment (such as shields) and so on. Keep fractions, if any.

Note that certain charms may allow you to ignore certain penalties that apply here.

Step C: Apply Magical DV modifiers

Add up all modifications from any charms that add or subtract set numbers from DV to get C, the total modification from charms. Keep fractions, if any. Do not apply "special" charm modifications of DV (see step E) or charms that eliminate penalties (see steps B and F).

Any charms claiming to add X to a defense pool instead add half of X to C.

Step D: Check Against DV Cap

Even though DV is no longer based on a dice pool, it is limited using half the typical formula for calculating dice limits. Call this value L and maintain fractions. If C is greater than L, set C to L. Apply C to the running DV total.

Step E: Apply Special Effects

Special effects are those that "cut DV in half", "reduce DV to zero", make certain defenses inapplicable or otherwise alter DV in some way other than simple addition or subtraction. Again, maintain fractions.

Step F: Apply Environmental Effects

Apply environmental effects like cover, terrain or high or low ground modifiers to DV. Note that certain charms may allow you to ignore certain penalties that apply here.

Step G: Round and Use

If the result is less than zero, make the DV zero. Finally, round DV as normal. Reduce the incoming attack by that many successes.

Pros and Cons

This method should be both more consistent and faster than the odd hybrid suggested by the rules, and can be made more so usingSuturedDefenseValue/SuccessConsistency. Unless modified by some of the other variations, some penalties (wounds, mobility) are mathematically twice as bad as similar penalties when used for attacking. Also, unlike attacking, you cannot transcend dice pool limits by buying successes.
