Version 0.13: This article may not be up to date for the latest stable release of Crawl.


An encumbrance rating is a penalty applied by almost all body armour and bardings. This is a measure of how much your defensive equipment gets in the way of your attacks, spellcasting, and attempts to evade enemy attacks. Multiple sources of encumbrance rating stack with each other. Shields also have a penalty, but it is handled differently and is never actually named in game.

In general, the heavier your equipment, the greater the encumbrance rating will be. You can reduce the impact of your encumbrance rating by increasing your strength or Armour; generally speaking, having strength equal to the item's encumbrance rating will significantly reduce the penalty it applies, though further strength will still provide you with diminishing returns.

See the Table of Armours for numerical details on all items with encumbrance ratings.

Penalties

Adjusted body armour penalty

Baseencpenalty.gif

Where b(S) is the base evasion penalty function over a scale, e is the encumbrance rating of the armour, S is an arbitrary scale the base is used at for the particular penalty, a is the armour skill of the subject, and s is the strength of the subject.

This penalty is not applied directly, rather it is necessary for calculating each individual penalty, which each have a specific scale they use for the S value.

Unarmed Combat speed penalty

1d10 + 2d(Adjusted body armour penalty) - 10

If this amount is greater than zero, it is added to your unarmed combat attack delay (in auts).

Armour to hit penalty

1d(Adjusted body armour penalty)

This amount reduces the accuracy of your melee attacks and decreases the chance of performing an unarmed auxiliary attack without the corresponding mutation.

Adjusted evasion penalty

Barding ER/3 + Adjusted body armour penalty

This amount is subtracted from your evasion before applying a stepdown function.

Dodging penalty

AdjustedDodgePenalty.gif

This penalty makes it harder to get some evasion from your dodging skill, and does nothing if you have not trained that skill.

The dodge penalty is only applied if the encumbrance rating is over 3, at which point if your strength is lower than the encumbrance rating then this is subtracted from your dodge bonus, otherwise if your strength is larger or equal to the encumbrance rating then your dodge bonus is scaled by the penalty.

Stealth penalty

2 × (body armour encumbrance rating)2 / 3

This amount is subtracted from your stealth score.

Spellcasting penalty

25×Adjusted body armour penalty - Racial bonus + 25×Shield penalty - 20

If this amount is positive it is added to your failure chance. See spell success for more information.

History

Encumbrance ratings were introduced in 0.13, replacing the EV penalty system.
