Beyond the Wall doesn’t normally have any rules for criticals (success or failure) or for gear damage. But, pursuant to my last couple of posts, I’d like to increase item turnover and adding those seems like a good first step for doing so. These are optional rules for Beyond the Wall (or any other low fantasy d20 game, particularly ones that don’t already have critical rules). They add some extra combat complication, but are likely to be rare enough occurrences (and mostly player-directed) that it shouldn’t slow down play too much to reference them when they do come up.

Critical Results

The Success Hierarchy

Whenever the rules below refer to stepping up or down a level of success, they’re referring to the following progression:

  • Critical Success: Usually has twice the normal level of success
  • Success: A normal successful result
  • Partial Success: Usually has half the normal level of success, or success with consequences
  • Failure: A normal unsuccessful result
  • Critical Failure: A really bad failure

When rolling normally, a partial success is only possible if a result steps up a failure or steps down a success. If you’re using the rules for acting cautiously, it also occurs when one die succeeds and the other fails. Remember that, when acting cautiously, you have to get double 20s or double 1s to trigger a critical result.

According to the normal Beyond the Wall rules, an extreme result automatically succeeds or fails (e.g., 20 always succeeds on attacks and saves, and always fails on ability checks). Under these rules, an extreme result also triggers a critical result, unless there was no chance of success or failure except for the automatic one. For example, if your modified target number for an ability check is 20+, a 20 still fails but is not a critical failure. Similarly, if a low ability and high difficulty modifier have reduced your chance of success to 0 or less, a 1 still succeeds but is not a critical success. This will usually not come up for attacks and saves, but applies if it does.

Critical Success

A critical success usually has twice the normal effect.

  • For ability checks, it has twice the normal effect: either significantly better success, half the normal time, or half the normal materials depending on what makes the most sense to the GM.
  • For saves, not only was the dangerous effect avoided, but the character gains a +2 bonus that can be used within the next round to attack or circumvent the source that triggered the save (e.g., +2 to attack the caster of a spell,  +2 to a check to disarm or bypass a trap, etc.)
  • For attacks, it does double damage (just double the rolled total rather than rolling twice).

Critical Failure

A critical failure may result in something unusually bad happening from a failure.

For ability checks and saves, it presents the GM an opportunity: if the GM offers the failing character a fortune point, and it is accepted, the GM may narrate a particularly bad level of failure. Players may not spend fortune points to reroll after accepting a critical failure opportunity, and are stuck with whatever the GM describes. A player in direct opposition to an NPC may pay one of her own fortune points to trigger an opportunity caused by that NPC (the NPC does not get the fortune point, it is just spent); this will usually only happen when the player does something that forces the NPC to save, or the player is in a contested ability check of some kind with the NPC.

For attacks, a critical failure forces the character to roll for a fumble result. Roll 2d20 as if acting cautiously, attempting to get 11+ for a success, and compare the result to the following chart:

  • Critical Success: You are knocked fortuitously off-balance, and gain a +2 to your next attack against the same target within a round.
  • Success: Your failure is a normal one, with no additional effect.
  • Partial Success: You are knocked off-balance, and take a -2 to all attacks until you spend a round recovering your balance (this is cumulative if you suffer multiple off-balance results before taking time to recover).
  • Failure: You are disarmed. It will take you a full round to recover your weapon (and certain terrain may make this even harder).
  • Critical Failure: Your weapon is broken and useless until repaired.

Other Sources of Gear Damage

Sacrifice Weapon

After rolling an attack (but before rolling damage), you may choose to have your weapon break to increase the level of success by one step (i.e., a failure becomes a partial success, a partial success becomes a full success, or a full success becomes a critical success). The attack does its damage and then the weapon is broken; you are essentially breaking your weapon for additional force or advantage. At the GM’s option, this may not work for weapons harvested from the environment for free (because they’re not brittle enough to shatter, and also because this is a rule designed to actually cost the player something), or weapons that are unbreakable.

Sacrifice Shield

After an attack is rolled against you (but before damage is rolled), you may choose to have your shield break to decrease the level of success by a number of steps equal to the shield’s AC bonus (e.g., a +2 AC reinforced shield turns a critical success into a partial success and a partial success into a critical failure, while a regular +1 AC shield only reduces a critical success to a regular success or a partial success into a failure). The GM may choose to have this not work against certain attacks that would bypass the shield

You may also use this option on saves made against a source that could logically be blocked by a shield (e.g., breath weapons, traps, etc.). In that case, step up your save’s level of success by the shield’s AC bonus.

Sacrifice Armor

After an attack deals damage to you, you may choose to have your armor break to reduce the damage. Divide the dealt damage by the AC bonus of your armor (e.g., by two for +2 leather armor, by four for +4 chain, etc.). You lose the armor’s AC bonus for subsequent attacks until the armor is repaired.

Attack to Strike a Weapon

As a combat option, you may make an attack to strike your opponent’s weapon instead of the opponent. Make an attack against the target’s Strength or Dexterity (whichever is higher). Use the opposite of the fumble chart for your result (i.e., fumble gives the target a bonus, failure has no effect, partial success knocks the target off balance, success disarms the target, and critical success breaks the target’s weapon). If your weapon’s damage die is smaller than the target’s, reduce your success by one step (it’s hard to disarm or break a sword with a dagger). If you’re wielding your weapon in two hands and the target is not, increase your success by one step (it’s easy to disarm or break a dagger with a greatsword).

The “Fragile” Quality

Some weapons may be considered “fragile.” This is common for primitive materials like glass, bone, and stone. Treat all “disarmed” results on fragile weapons as “broken.”

Nonsensical Results

Some results may not make sense for certain weapons. If a target has claws or other natural weapons, a disarm result doesn’t make sense. If the target’s weapon has the unbreakable ability, a break result doesn’t make sense. In these and similar cases, step down the result to the first result that does make sense.

Repairing and Refitting Gear


Weapons can only be repaired in the field if it makes logical sense (such as for hafted weapons in a forest with available woodworking tools).

Shields cannot be repaired in the field if broken.

Armor can be partially repaired in the field with an Intelligence (Smithing) check; in this case, it regains half its normal AC bonus. If the wearer chooses to sacrifice it again, it can only be repaired up to half that AC bonus, and so on (e.g., you can sacrifice a +4 AC chain armor twice in the field before it’s down to only +1 AC after repair and no longer worth sacrificing).

In town, a broken weapon, armor, or shield costs about half its normal value to repair (possibly less with a friendly smith or if the character has the skill and tools to try to repair it herself).


Found weapons and shields are generally usable by anyone (unless they are sized for particularly small or large creatures). Armor, however, is generally customized for an individual. Unless the GM decides that the armor was fitted to someone with almost exactly the same proportions as the character using it, treat it as broken when found (this is particularly true if it was looted from a slain opponent, who probably took some hits to it in the fight). As normal, the character may make an Intelligence (Smithing) check to try to “repair” it in the field (adjusting it so it can be worn with some benefit), and it costs half its base value to refit it in town.
